Great idea, should be combined with cuts to shaky hand-written black signs with white lettering saying "Clear the canvas!" and "Draw fifty-by-two-hundred rectangles"

Solitaire win screen - Procedural version

u/lewdev

That's amazing! You got 4 stacks of cards and had them randomly shoot out at random velocities, which is much more accurate to the original win screen.
u/tomxor

Thanks :D glad you noticed, I actually counted the L/R directions from videos to check the probability 3/4 left, but the velocities were mostly eyeballed. I also tried implementing with the full set of unicode cards, since they have a nice codepoint arrangement, but fromCodePoint just costs too much, and they are transparent, your choice of the joker was spot on visually.
u/ximavus

Its the new trend!

u/tomxor

Nostalgiac for me :D I think I chose +t*60 to get rid of the juddering. That doesn't help with sin here, but I think the actual reason for judder is from round-up aliasing on the left side of i/w+f^f, so pre-flooring f seems to mostly eliminate it e.g 999*S(t*.05)|0
