Alien or Puppet Master?

A few minutes of grainy, black and white video show a shadowy creature with big eyes peeping over a windowsill. But does it show a puppet or an alien from outer space?

The video, purportedly capturing proof of alien life, was released this morning during a press conference at the Tivoli Student Union on the Auraria campus in downtown Denver.

Over the course of three minutes or so, the footage shows a white creature with a balloon-shaped head that keeps popping up and down in a windowsill that was 8 feet above ground. The face was white, with large black eyes that seemed to blink.

The creature would slowly pop its head up and peer through the window then drop suddenly down, apparently trying to avoid detection. It raised its head up about a half dozen times. The alien's other body parts were not visible.

Here's my question: How is it that visitors from beyond space don't seam to possess surveillance technology better than a 15 year of Peeping Tom?
