Inspired by steampunk graphic novel The Five Fists of Science, Dr. Horrible Rob Flickenger set out to make his own handheld, field-generating Tesla coil gun.

He succeeded.

It's effectively a portable electrocution machine, with an arc draw of about 12 inches; "you pull the trigger," explains Flickenger, "and lightning comes out the front." It looks totally awesome and totally dangerous. He's posted build details over on his website, but this is one DIY project you might just want to enjoy via the internet. [dɸ/dt via boingboing]
