Try to hover over the circle! Doesn't work in fullscreen :'(

u/Jenky

Did make a more game-like version that did work fullscreen at 190 bytes, kept score and everything, but couldn't golf it any lower
u/Jenky

Also this one only works in Chrome again, thanks to e.pageX/pageY being slightly too long

Nice! You can also use & instead of | for a slightly different style. i&i/t is also good

u/recursive

Direct pixel manipulation. Interesting approach but it looks like it might always be larger. Does this have a dweeting application?
u/hypothete

I'm not sure. I put this one together in case people had ideas on how to shrink it.
u/veubeke

@hypothete new ImageData(W,H) saves some bytes as does incrementing i by 1 instead of 4 and calculating image data size manually. https://www.dwitter.net/d/2069
