That looks awesome. What's going to go in the bottles?
Some things I've seen (or used):
Clear beads, crystals, or marbles - these reflect the light around in interesting patterns.
Cotton gauze/fluff (like the stuff cotton balls are made of) - the cheapest LED diffusers ever :-P
Plastic film, folded, crumpled, or catch the light in interesting ways.
Flourescent material - the red/orange flourescents will glow under most blue LEDs, but not under the green and red. You might be able to get glow in the dark stuff to glow too under the blue.
