New iTunes Visualizers in Leopard
Lathe: A floating fountain of particles that pulsate to bass (very responsive to bass drums)
Jelly: A quick moving kaleidoscope of multicolored bright LED-looking lights
Stix: A streak of light that changes speed and color to the music and reflects on the "floor" of the visual.
Apple is expected to release Leopard in October.
