If you're going to post something that cool, you at least have to give us a glimpse of the control circuit or the schematic!!! Please!

Sure thing. I posted a schematic of the circuit and a list of the parts.

Thanks for all of the positive comments.

Thanks for the circuit and parts. But I don't see anything to make them flicker/flash in the circuit. Is that built into the LEDs? Where did you get your LEDs? Do you have a web site/link?

Yes, RGB (red blue green) leds have a tiny built in chip that causes them to shift between colors. The 5mm are generally rated for about 3v max, hence the resistors. You can buy slow fade that shift slowly, the ones I used shift quickly. I bought mine on ebay. Helps if you use a little sand paper on the leds to scratch them up; diffuses the light more across the crystal. By the way, the piece of crystal is a slice of Agate that a jeweler friend gave me.

That's awesome! I feel like I'm watching Avatar on acid. "I think the trees are talking!" "What are they saying?" "I don't know, but it's gotta be important! Trees don't just say anything!"

That is really neat. Truely intriguing. Two questions, if you don't mind:
What keeps the three LEDs in the same phase of color at the same time?
Why not use a 3V button battery and skip the resistors?

They're not in phase, each shifts color randomly. And each led needs 3v to operate correctly, so with 3 leds a 9v battery is perfect. The resistors just make sure each led isn't hit with the full 9 volts, which would burn them out.
