use a second sprite as a mask. put a 1 everywhere you want to see
through and a 0 where you want it to block. and the mask to the screen,
then or (or xor) the image over it.
alternatively, you could split the image into horizontal runs, each
having a start offset and a length

ooh, spinning... that takes trig!
i would suggest, if possible, to store a copy of the sprite in each
direction it needs to point
