Starting this post on a (peripherally) musical note:

Dance Dance Revolution is all well and good, i suppose - but it's a bit tiring, and really not something you can do at the office.

So here's a solution to both of those problems - the DanceMat USB device!

It plugs into your computer, which provides music and sound effects ... and notice that it even includes a Desiree Cousteau look-alike cardboard character to set the proper mood. (One might think there'd be a John Travolta look-alike, too, but apparently there isn't.)

WHile the DanceMat might be a bit offensive to fellow cube rats, with its music and noise, the next two widgets are a bit less passively offensive:

The Laser-Guided USB Desktop Missile Launcher, and/or

The Webcam-Equipped USB Missile Launcher! (Which can be remotely controlled over a network for those sneak attacks so vital to the prosecution of everyday corporate wars.)

Both Launchers have a range of up to 15 feet, and are controlled from your computer

Now, this one actually has a legitimate purpose - but it's still nicely calculated to bug your fellow workers (or other users of your home computer):

The Doomsday Device USB hub!

Not only does this sinister-looking little beauty have multiple switches (one of them is even a key!) that must be operated in the correct order in order for it to carry out its Evil Purpose, a Big Red Button and sound effects indicative of something, somewhere, blowing up - but it's also a fully-functional four-port USB hub (In case you don't have enough ports for the launchers and dance pad).

Not a USB device, but just as useful for annoying others, and relieving your own tensions is

The Pocket Bubble-Wrap Simulator Keychain!

Yes, now you too can have the Bubble-Wrap of Eternal Poppishness for your very own!

But wait! There's more!

Every hundredth pop isn't a pop - it's some other random sound effect!

Most of the above are from the "Gadgets" section of ThinkGeek, where many Wonderful Things may be found...
