This isn't the first time that Terren has made a Tesla coil Christmas tree, nor do I think it will be the last. He uses slow exposure photography to capture these incredible image, taking about two minutes for each of the shots. You can check out his site for some behind-the-scenes pictures of how he arranged the project and the safety measures he took while working with this coil.

In the meantime, I'll just be here ooh-ing and aaahh-ing for a while. [Tesla Down Under via Neatorama via Make]

All you need to do is download the PDF, print it out on card stock, cut it out, tape the ends closed and ipop some LEDs in there for color. As you can see in the image above, the light filtered through the layers throws a festive pattern on the walls. [Sparkle Labs]

The 700 LED lights on this particular city's Christmas tree are not connected to any sort of traditional power outlet, instead relying completely on volunteers pushing the pedals of some stationary bicycles. It's certainly environmentally friendly, but will they seriously manage to consistently keep 15 people working out? [CNET]

Wired does not.

Like the Wizard of Oz, the workings are hidden behind a curtain. One thing we do know — there is either cheating or batteries involved. I've walked by a few times to see nobody on the bikes, but the lights still blazing.

Perhaps the tree is powered by Christmas spirit? [Wired]

However, constructing the tree was done at the expense of a thorough DoD level wipe, so this innocent little project may contain enough sensitive company data to make Trigger's bosses go Grinch on his ass this year. [Make]

Each one is hand painted, and we're thinking that Art and his Ukrainian minions have done such a good job of camouflaging these ornaments, if you put them on your Christmas tree you won't be able to see them at all.

Sure, it would have been cool for the tree to be fully animated, with characters moving freely around the tree. But for now, we'll just appreciate the time honored tradition of ghost chomping. Between the tree and his Christmas special that's on Cartoon Network every year, Pac-Man clearly loves the holidays. [Clipset via Technabob]

What do people who buy stuff like this put on the top of the tree, I wonder? [Nigel's Eco Store via Gadgets News]

The move is expected to reduce the display's electricity consumption from 3,510 to 1,297 kilowatt hours per day. And if that wasn't green enough for you, the tree will also be recycled into building materials to be used by Habitat for Humanity. And the branches will probably be used in a nutrient-rich mulch that will nourish mother Earth, hippies will dance and sing—and so on and so forth. The lighting ceremony takes place on November 28, and the tree will be illuminated daily through the first week of January. [CNN]

Might as well make tree life support a little easier. This thing might look like a big present, but it's really just full of water. A tube runs from it into the tree's water reservoir, keeping it hydrated so you no longer have to deal with watering it on a daily basis. Just be prepared for a really disappointed kid when he opens this thing up Christmas morning and finds a few gallons of tepid water rather than the PS3 he asked for. –Adam Frucci

If our experience with cheap voice-control devices in the past is any indication, you might be doing a lot of futile shouting at the wall with this thing. But it might even be too sensitive. In that case, to keep the lights from turning off every two seconds here at Gizmodo HQ, we'll be sure not to pre-program the words STFU. – Charlie White

It's yours for $24. Good grief. But I like it. And no, the psychiatrist is not in. – Charlie White
