Are you sick of all the cutesie little iPod covers for your first generation Nano?  I'm not, but these little guys are so mean and scary, it's adorable. 

What are they:  Nanomonsters. 

What do they do:  Keep your Nano warm with a little rubber bodysuit while looking scary cute. 

There are eight different characters, from Mitts, the evil pink bunny (my favorite) to T-bone the pirate and Skully the skeleton.  The opening at the bottom allows for you to plug in your headphones & iPod charger, but when nothing is plugged in, they stand up on their own.   Plus, one of their "hands" is a hook to attach to your clothes or bag.

Never again will I have to worry about dropping my iPod on the treadmill while I'm working out, because they are made of rubber and will bounce right back.  There is no screen or Click-Wheel cover though, so scratches are still possible.  Who cares, they look cool, and that is the most important thing after all.
