Extra credit: Before coloring, try switching to HSB. Copy the Brightness channel to the Saturation Channel. Tone it down (drop the brightness, or use the graduated bar in Levels.)
Goto the HSB channel. Total noise. Gass Blur 3. Equalize. Switch back to RGB now or create a gray AliSyn (alien synapses). Psycho wowie!
Play with the selection channel for more 'delic eye candy.
