Oh definately! It was just a prop piece though, which means I couldn't spend too much time on it! :(

 Then maybe it's because the animation is too fast... But I still say that this could be improved.

 The light source seems to hold fine, as I flipped the images to remain with the lighter areas to stay on the top and right side!

However, yeah, the notion of direction is lost a little by keeping the images to a minimum, however in-game, it isn't too noticable. This is the exact same method Sonic 3 done with the bricks that are pushed out of the wall in Hydrocity Act 1! It looks fairly well when all together with it's other animations!

 By using just two images and inverting them (and so not changing the light source) you take away the notion of direction in which the brick is rotating.
