As demonstrated here, I've got a jones for real-world robotics (or at least things that look like real-world robotics). Here's two of the coolest, freakiest robots yet created:

A real-life Transformer, as demonstrated at what looks like a Japanese electronics show. Look at that thing go! And when can I buy one?

The "Robotic Mule," which simultaneously fascinated me and gave me a serious case of the creeps. Seriously, check out the video and see how it moves. It's eerie, right? Now imagine it heading straight for you, intending to kill you. Yeah, you'll have nightmares tonight. You're welcome.
