Long hold times with Symantec have left me with a certain amount of "free time" this afternoon... It works pretty well, though I did smash the ever living daylights out of my knuckle!
Our office "Safety Coordinator" was the one that gave me the idea (mine was built from her design and hers' was designed from here.) I added the handle, and the binder-clip saddle which makes it much more usable!
She later came in and supplied me with projectiles. Chopsticks! Already put a hole in the wall, so yea, it works good!
