Thought I might mention "Animated BitMaps" by Scott Boyd, Page 67 of MacTutor
July 1987 (V3#7).  He describes several algorithms, and gives source code for
one which requires one full-screen-size offscreen bitmap, small offscreen
bitmaps for the object and its shadow, and two small scratch bitmaps.
