I hope Santa's careful around Peter Terren's Christmas tree, because it's a Tesla coil with some color filters set up to make all the sparks, zaps, and electric arcs look oh-so-pretty. Yes, it's oh-so-pretty and oh-so-potentially-deadly.

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]
