An animation: calls f(t) for n values of t from tmin to tmax, each call drawing one frame with draw()/text()/... (only the finished animation shows, not each frame). Set the view first with xrange()/yrange() -- inside quiet { } so they show nothing themselves -- so it stays still.
tmin (number) -- tmax (number) -- n (number) -- framesf (function) -- f(t) draws one frameFrame-by-frame animation with memory, like Processing: setup() runs once -- what it draws is the background of every frame, and what it returns is the starting state -- then draw(i, state) draws frame i (0 to n-1) and returns the next state. sketch(n, draw) with draw(i) alone works too. An optional last argument sets the speed in frames per second (1-60).
