Hi everyone. Earlier in the thread someone mentioned using flickering LED "candles" as a light source to get the swirly power effect.
FWIW, I found a set of two such lights at Hobby Lobby for $2. (The online store only has
this 6 pack.)
The "flame" part pops off easily if you come at it from the side. The case itself is a cheap, thin plastic and you can get into it easily. Be careful not to snag any wires though. Just remove the upper part of the case until you can see the guts. You're left with a CR2032 coin cell battery, a switch, and two wires soldered to the yellowish LED. The switch's box appears to contain all the circuits needed to make the LED flicker intermittently, because that's the only real component in there.
If you want a Tesseract like the films, you can easily remove the yellow LED and replace it with a 3V blue one. That should give you the correct color and keep the flickering effect intact. (I haven't tried this.)
There isn't really a battery holder for the CR2032: It's just two wires with bent metal to make a connection. The good news is that you can replace this setup with a coin cell holder from Radio Shack, or if you need more than 72 hours of light*, any other battery holder that will provide 3V. I tried a 2xAA battery holder and it worked.
(I can provide pictures if you want, but really the thing is so simple I don't think you'd gain much by seeing them.)
Hopefully someone will find this useful.

*The packaging claims each LED tea light will provide 72 hours of illumination. I can't comment on that.
