This project demonstrates a simple use of rotation centers. Press space, and the sprite should appear to move around the screen. The sprite doesn't actually change position, though - its costume's rotation center is simply changing. (NB: This works for bitmap costumes too. There's a sprite with bitmap versions of the same costumes too; see inside to unhide it if you like.) You can also press A (and B if you've shown the bitmap sprite) to demonstrate why the term is "rotation center"!
