I don't know if anyone has seen this, but thinkgeek.com has firefiles in a jar:

Haha. That's pretty cool. Living where I do, I've never seen real fireflies.

That's really cool! I wonder if someone on the thread can build one cheaper?

I like the fire flies.
I got the butterfly in a jar and it is cool.It moves just like a real one.

I wonder if you could make one using a small motorized FCG type mechanism?
Have it move yellow LEDs up and down, or use a UV LED for illumination of UV reactive fireflies moving.
Just a thought.

looks to me like the fade is a little too slow. also, the movement should be quicker and more erratic. and the uv led with reactive fireflies sounds cool, but how do you turn some of them on instead of all of them? it seems to me i once saw something like this using muscle wire springs with seed lights at the ends. i'm going to try to find that.
