Repel the Mouse
A grid of circles try to move away from the mouse as you mouse over them. This was inspired by an example in "Flash Math Creativity" published by Friends of Ed.
This was a test to synchronization a declared animation with sound (all SMIL).
Once the red circle appears, click it to view (and hear) the animation. Please note that this sample uses the audio extension defined in the Adobe SVG Viewer so sound is only available in that line of viewers.
