no fuckin clue how i got this in 81 characters
u/Qwitter

if you send a single pixel across the screen at this resolution (70) like fillRect(X+t,,1,1,1) you can see how the canvas has a smoothing effect by slowly pouring the alpha = 255 value between the pixels

this is supposed to be water in the sun, but i couldn't figure out how to make the color blue instead of rainbow without ruining the shine.. any ideas?

u/danny@hille.dk

You can do it the lazy way, by simply adjusting the number range to lay within a single color hue, and shifting it towards the blue hue, blue is around 165 (light greenish blue) to 260(purplish blue)
u/danny@hille.dk

But i actually like the rainbow water better :-)

lol thanks! :)
