Vanessa Ezekowitz 46cbc76988 make "on" water turbine animated!
This uses a fairly simple trick: the textures are animated, while the
model is static and has a number of rotated copies of the parts that are
seen to move (four copies of the blades, eight copies of the top/bottom
and their edges).  The opaque parts of the textures then decide which of
those faces' copies are visible in each frame.
