Moldable Silicone = Hacking Fun

I've recently discovered this product called sugru, and it seems pretty awesome. It's pretty much moldable silicone that cures at room temperature. Imagine the cool hacks you could do with it... custom rubber grips, patching leaky... things, custom rubber cases for certain death-grip phones. I almost want to buy some just to see what all I can do with the stuff! I definitely have ideas for improving the crappy grips on my Pilot Hi-Tec-C Coleto and Uni-ball Jetstream 2 & 1 multi-function pens.

On the sugru site, they even have a gallery of hacking ideas for you, in case you run out.

Anyone else out there have any cool ideas or uses for this stuff?
