91 map

I played the game 91 and wanted to create a map of the world. What started out as a simple map to help keep track of the regions soon turned into a larger project which resulted in an A0 sized poster being produced. The creator of the game got in touch and at the time of writing the first poster has been printed and more will follow. The creator is going to publish and sell these posters online.

Alarm clock

This project was written very quickly one evening to give myself an emergency alarm clock after my phone was stolen. As a result it is not very user friendly.

Apollonian gasket generator

One of my hobbies is creating fractals and one of the most interesting is the Apollonian gasket. An area defined by some arcs and straight lines is recursively filled with circles and in all cases (except the trivial case of a single circle) this process recurses infinitely, making counting circles challenging.

ASCII art generator

After talking to a friend who suggested I write a text based adventure game, I decided that it would be useful to develop a way to generate graphics that could be displayed as text. To achieve this I used the HTML canvas to analyse images and comapared the distribution of colours with various characters, providing graphical, textual, and HTML outputs.

Box filler

This is a rather frivolous script I wrote to serve some sort of purpose, but I forget exactly what that purpose was. I think it may have been to create a random sitemap using images from various pages. It takes rectangular array of squares and fills it with squares (or boxes) of random sizes. Then to make it look more attractive it fills each rectangle with a picture from placekitten.

Box plotter

One of the most popular ways to compare results in particle physics is to create plots that show different results with horizontal bands (sometimes known as boxes), making comparisons easier on the eye. Unsatisfied with the quality of available solutions at the time, I created my own scripts which would make these plots for use in my thesis.

Photo calendar

One of my friends suggested I make a calendar featuring some of the photos I had taken while in Geneva. Here is the result. She wanted me to make some money from it, but I didn't the quality of the images was good enough, so instead I just made it available for free. Future years might see a paid option.

This page contains some simple ciphers. This was going to be extended to include some more sophisticated ciphers, but I didn't have the time or incentive to develop this page further.

Circle from three points

This project was thrown together rather quickly to solve a geometrical problem: How can you analytically find the circle which passes through three given points? The construction simply demonstrates that the method works, and it not intended to give any further information to the user.

Color converter

This is a very simple yet useful script for converting colours from one description to another. What causes the most frustration here is the difference between US and UK English, as it seems I'll never be happy with the uri for this tool. So I use the word "color" in the context of values the computer understands and "colour" to describe the aesthetic experience of humans. That makes the best of a bad situation.

Complex polynomial

On the Numberphile YouTube channel I saw a video that gave a proof that all complex polynomials have at least one solution. The method involved moving one point about the complex plane while another is mapped around a path elsewhere in the plane. I decided to map this out using Javascript!

Conway's Game of Life

Conway's game of life is a very famous mathematical model with a rich variety of "creatures" that can interact with one another. This script is a simple interactive sandbox where the user can "paint" cells to create different shapes. There are a number of predefined boards that the user can choose to investigate some small and interesting patterns as they evolve.

Crazy 2014

When I heard the sad news about flight MH17 I couldn't quite understand what was happening. It seemed like the worst parts of 2014 had come together in a way that nobody could have predicted. I tried to sum up the situation in this infographic. This mini project was in fact an excuse to practice some infographic making skills, which I had not used for a long time.

This project is a rewrite of a previous project. It emulates the popular dice game, Yahtzee. This game previusly used PHP, but was converted to Javascript once I became sufficiently skilled to rewrite it.

Dr Who: White people dance

I had had an idea for a very long time, which was to animate a song using the canvas and a YouTube video. Someone sent a gif image of some Dr Who actors dancing badly, and I saw this as an opportunity to test out my idea in the simplest way possible. So I put the gif together with the YouTube song and button to play/stop the music and animation.

General election data

This project displays the results of the 2010 UK General Electrion, and it was to be the first of many that investigate different data sets. One of my planned meta projects is to make the acquisition, storage, and analysis of public domain data simpler and easier. This was an experimental project, and created in a hurry.

Room explorer game

This project is a game where the player explores rooms with a top down view and does all the normal things, such as traverse mazes, open doors, fight monsters and so on. This is a gravity-less version of the Platform game and has an even more retro feel to it. It's obviously a work in progress and needs a lot more work, but the main mechanics are complete and it even has its own editor.

Eye of Argon acronym generator

This project was made to demonstrate a point. A student said that they doubted I could make a simple application in an afternoon, so within about an hour I had made this is. It takes a string from the user and makes a phrase using word from the Eye of Argon to make an initialisation.

Feynman diagram maker

One of the most common diagrams that particle physicists use are Feynman diagrams. There are already a few tools that can be used to make them, but they usually have some significant drawback (including non-intuitive interface, poor quality graphics, lack of control over the final image, text only input.) This is a drag and drop style Feynman diagram maker aimed at making creation of the diagrams as quick and simple as possible. This is quite an advanced project with lots of scope for further development.

This project was made partly to combine the Hexagonal civ game with Google Maps, and partly to push the Google maps API to its limits. It turns out that Google Maps is not suited to this heavy use.

i, short for indico

At CERN we used a meeting organisation system called indico. Each meeting had a unique ID that was used to identify the resources associated with it. In many instances there were times when a person had to access a meeting page when they only knew the unique id, and not the full uri. I made this tool to obtain the full uri, given only the meeting id. Since this project shortens the uri for indico it is called "\(i\)", which leads to all kinds of puns.

Geneva Marathon analysis

In 2013 I took part in the Geneva Relay Marathon with some friends. The results were presented, leg by leg, on a webpage. I took this as an opporrtunity to analyse some data and find a novel way to display the data.

Marble Hornets

Marble Hornets was a webseries that spans the course of about five years. The premise of the series is that a student film maker started filming an amateur movie in 2006, but abandoned the film due to "unworkable conditions on set". It quickly turns into a horror series that brings with some novel techniques. However what really inspired me to make this project was the asynchronous storytelling narrative, which requires the viewer to piece together the true chronology based on the context of the videos. I'm an active participant on one of the busiest discussion boards for this series and regularly update this project as each new video is released.

Maze - Island Quest

Following on from the Platform game and Explorer game I wanted to create a tile based game. This was partly inspired by the game Kharne which I had played many times, and I became frustrated with the lack of similar games online. (It was this frustration that lead to a minor obsession with 91, and the creation of the huge 91 map poster.)

Only Connect Missing Vowels game

Moving very slowly!

One of my friends challenged me to write an app that play clips from the Strong Bad song "Moving very slowly!" Of course within an hour I had a working webpage that did just that. This was mostly a matter of refactoring the Advent Calendar with a few tweaks.

Neuron simulator

One of my friends wanted to develop a genetic algorithm that was capable of learning and adjusting a neuronal network to suit its environment. I got as far as making a genetic algorithm before abandoning the project as my friend's interest seemed to move at the same time as my knowledge of the problem was exhausted.

Pebbling a Chessboard

One of the channels I follow on YouTube is called Numberphile, and they give plenty of good ideas for mathematical games. In this game the user has to move pieces around a chessboard in order to liberate "clones" from a prison. On Numberphile, they suggested playing this game using an actual chessboard, but I decided that a better way to do it would be to write my own game. So here it is.

pi estimation

Generic platform game

This project is something I've been working for a long time and something I have wanted to develop for as long as I can remember. It's a platform game strongly inspired by the BBC Micro game, Citadel. (I have another project dedicated to mapping Citadel.) When I was younger I would dream about playing non-existant extra levels in Citadel, and when I started recreational programming I would sometimes dream about making new levels for the game.

Generic block stacking game

This was my first serious Javascript project which was written some time in 2009. I chose to write a Tetris clone because it was a well defined project that would teach me how to use Javascript. In addition to Tetris I also made Tritris and Pentris to see how well balanced the three games are compared to each other. It turns out that Tetris is about right, with Tritris being too easy and Pentris being too hard.

When I discovered I could manipulate images with PHP one of the first things I wanted to do was perform coordinate transformations.
