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.
171: for(F=255,P=F*F;--P;x.fillStyle=c,x.fillRect(X*8,y*5,8,5))for(X=P%F,y=P/F,c=0,D=9;!c;++D)v=X-D,c=v<0?y*D+y+X&F?R(C,y,y):'white':(K=(y*D/F|v*D/F)&D+frame,K&16&&R(K*=4,K,K)) (trying to eventually fit a bob)
There's enough space to fit a jump/hop/bob, but I couldn't figure out the right period to pass into S.
