With the impending full launch of Impulse, we've been having some fun with Impulse-related skins.  Yesterday, Seabass posted an Impulse themed cursor set he's been working on in his spare time (yes, in addition to providing fine technical support, he also does 3d art and animation).

The Impulse cursor set is built for CursorFX and is packed with animations.  If you watch the ball closely, you'll see that the core shown through the lightning bolt cut-out is constantly in motion.

Give the set a try, it's definitely a cool one.
