Usage notes
Because some browsers - *cough* Firefox *cough* - are much slower than others at executing JavaScript (yes, I concede that my algorithms aren't too optimised either...), using the Clear All and Fill All commands can take a long time on larger grids.
Larger colour coefficients produce some odd behaviour in the patterns that emerge (try using Fill All to see the whole pattern quickly [or slowly if you're in Firefox]). When you enter a new colour coefficient, my program uses it as a dumb constant to help determine the colour of each pixel (the other factors are the co-ordinates of the pixel and, when using the brush the number of pixels that have already been modified). I hope to get it to produce more complex/awesome ones later by changing it from a constant to a value that changes with time and the brush's co-ordinate position. The current colour behaviour is uninspiring.
