    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.

Twisted metal remix #uncompressed

u/danny@hille.dk

This is a personal thing!!! Twister2d is one of my favorite old school effects, it's also one of the first things i tried to golf to fit into a dweet (and I failed miserably :-)) I have retried tried (and failed) a couple of times, but this is the first time i actually managed to get the damn thing to fit without compression. I had to scarifice colors to maintin an interesting animation. Perhaps I'll get it next time :-) #twister #twister2d
