    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.

I was aiming for a #micelle using something like SPH, it arguably looks a bit like that after 30 seconds... or maybe an amoeba. It's not very SPH, basically just n-body with verlet integration and this simple pairwise constraint: k*(r-48)**3 where r is the distance between the particles and k is a stiffness parameter.
u/nburn42

How do you encode that? I tired for a little while to build something to do it, but failed.
u/nburn42

I'll try again later and I'll get it eventually, but it would be nice if there was some tool somewhere.

d/11852 to get the source just replace eval with throw
