      Just those of us without cubicles. I was thinking more along the lines of, "hmmm, I could use one of these , but with a taser gun, mounted on the roof of my vehicle to shoot small animals that want to put paw prints all over it." Then I was thinking, "hmmm, I wonder if anyone from PETA is going to read this post."

      I was thinking the whole paintball thing as well. Just like Team Fortress Classic (which I still love and play). This would add some serious fun to paintball matches, with each team getting one SG, playing Capture the Flag, and a hit means you sit out for 5 minutes. Literally TFC in the real world. Man, where do I sign up?

      Now if someone could built a device that would let me actually rocket jump. And survive. ;)

      Yeah and perhaps some sort of powerful shield, and replace the gun with some sort of Sharkbrand(tm) Laser and add a speaker that barks "exterminate" or something. We could call it a doorleck or darlink, I don't know I'll let marketing figure it out.
