instead of that, once it goes beyond 1000, start over at 0. then whenever you
want to have a certain previous image, such as 666 frames ago, instead of
saying that you want frame 1000-666=334, say you want frame N-666 mod 1001,
current frame number
i say 1001 just because you say that the first index is 0 and the last index is
1000, which means 1001 different indices, not 1000.
