    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Stargate Transportation Rings

u/Agnes

The teleporter rings are very Stargate SG-1, but I also applaud the set design in the background for looking approximately as good as Stargate SG-1's CGI
u/tomxor

Thanks. CGI was hard in the 90s

u/tomxor

True, Pavel's dweets are pretty tight. Usually the most I can hope for is -1 char :P
u/tomxor

d/24387 restored the slow draw, and removed the for loop for only +1 char

It's crazy how long this dweet chain is!
u/erin

holy shit!!
u/erin

this is amazing!
u/tomxor

Thanks man :) I like the idea
u/erin

i'm the type of person to come up with stuff by just messing with values.. so i kinda found myself making something similar to waves in a ocean and then i further explored the idea
u/erin

maybe this is why my dweets are so remixable.. they're fun to insert functions into :)

#nbody #gravity

u/tomxor

This is not very accurate of course, in particular it has quite bad iteration bias - and it's possible my math is wrong. It kinda looks right though I think.
