This is just hilarious. Even more so than the World Of Warcraft treadmill race across Azeroth. It’s a human-powered mobile treadmill by Alex Astilean. Technically the equivalent of a large hamster wheel for humans, this mobile treadmill will have everyone in the park giving you funny looks. Just be careful not to hit anyone. With the momentum this thing could potentially build up, who knows what kind of damage it could do?
