I'm in the market for a screensaver to top off my desktop. What I want is the screensaver to show the desktop as is, but then flicker and roll like a television that's getting bad reception, or like in horror movies when aliens or ghosts are nearby and the television glitches out.

Here are a few examples:
YouTube - TV Reception BAD
YouTube - After Effects - Marine View (Bad Reception)

Or even a creepy one like this
YouTube - Supernatural Interference

If it hasn't been seen before, how do I go about making it myself?

I only have a little background into flash, but that looks sweet.
