Like bears in tutus, 8x8 Tatra 813s are not the best dancers. You'll see what I mean when you watch these 30-ton machines attempt a beautifully choreographed ballet on ice.

These are the same kinds of trucks you see hauling themselves around obstacle courses in truck trials, only this time some teams decided to let their hair down and tie eight little ballerina slippers to their heavy-duty competition machines.
