You may recall the Dalek Pumpkin from 2006, the Snap-o-Lantern from 2007, and the Dark Detecting Jack-o-Lantern from 2008. The fertile minds at Evil Mad Scientist Laboratories have announced their Halloween pumpkin project for 2009, and it’s a winner!

The Rovin' Pumpkin' is a simple robotic pumpkin, and a close cousin of the Snap-O-Lantern. Silently, it sits on your porch-- camouflaged amongst the humble squashes.
After a minute, its green eyes start to glow, and it creeps... moving about one foot to the left... and stops. The eyes go dark again. It fades into the darkness. And it waits.
After several minutes and several steps, it reverses direction, and begins to creep the other way. Hopefully before it falls off of your porch.
