Want to see what you get when you combine a ninja with a cameraman? Just look at Florian Hatwagner, a Vienna, Austria-based camera operator who goes by the name "gimbalninja" online.

"I'm an Austria based cameraman that specializes in operating a camera whilst running, jumping and leaping over obstacles," he says.

Professional free runner Jason Paul recently teamed up with Red Bull to create this wild optical illusion video that you have to see to believe -- or not. The video’s description says that “Life as a free runner means the world is your playground… or is it just one big illusion?” It's a mind-bending visual experience that will have your brain questioning reality.
