Here's the video to a very interesting project by Justin Jensen, a mechanical engineer from Austin, TX. Definitely the best idea I saw since a long time ago - roller skates for a GorillaPod. What I like most is the fact that you don't need to buy an extra slider and carry around tons of equipment with you. This product is super simple, small and as it works with 3 wheels instead of 4 you can roll over bent surfaces, too!
Definitely something you should support. So please visit this site for more information.
