Here’s a computer mouse that doesn’t require tabletop space. This new gadget works just like any other optical mouse, but you just hold it in your hand instead. The ergonomic mouse plugs into your USB port. This would be a cool gadget for using during multi-media presentations or just for impressing your friends around the office. It’s tiny too, so it might make a good travel mouse to use with your notebook computer.

I found this new gadget at KlearGear.Com for $21.95.

Oh, the things you can do with a little creativity and a couple USB ports. The “Crunching Dogs” USB gadgets workout, tirelessly doing ab crunches while plugged in to your computer’s USB port.

Of all the USB gadgets I’ve seen, including coffee warmers and mini-vacuum cleaners, I think the “Crunching Dogs” have the most personality- by far. But, according to Coolest-Gadgets, these little guys have no on/off switch, so you may have to eventually pull the plug on them if you want to get any work done. However, I bet everyone at the office will somehow be jealous of these four-legged USB accessories, even if they occasionally get annoying. These USB dogs are available at Think Geek for $9.99 each.
