Cyclic buffers? At least in audio it's common to play buffer samples
in a loop and even play them in reverse. I'd imagine internally C/++
apps just have an index which is inc/dec'remented based on a setting,
and once the index is 0 or lengthOf(array) and depending on the
reverse switch the index is reset to its beginning position.
