It's been around for a couple of years and is called Freefall! https://itunes.apple.com/us/app/freefall!/id416974946?ls=1&mt=8 But I hear they had to say jump instead of throw as apple originally rejected it! It even has a leaderboard.

Well this is how I see it. 1) Single frames easy to fake. No brainer. 2) Movies harder to fake, but still take a bit of time and you can probably make something look believable. 3) But require someone to create a fake video in less than 3 seconds, when they only find out what the video needs to show at the start of the recording. Thats sounds pretty damn hard to me! This is what http://gestya.me/ claim to do - so does anyone think they could get around this?

Imagine if you could see what the owner of the account looked like.. Gestya suggests you can. Then all you need to do is to see if they look like a robot or a real person!
