Towering above San Francisco, glowing Tetris pieces gently fall into place like just as they were fated since birth. But at the street level level, skateboard Tetris is a different, more intense experience.

The skaters spin through nearly pitch black streets, donning glowing wireframe Tetris blocks for a hats. And then, at the last moment, they need to negotiate just how they'll fit with all those other Tetris block heads on wheels.

But...as long as no one was hurt...we wouldn't mind seeing the effect recreated in an empty swimming pool. [TechEBlog via technabob]
