It's an interactive video where you play the piano by using the timeline. Brought to you by Instrumentube. Under their profile page they've also got an electric guitar, bass guitar, upright bass and shaker. You can start your own band on YouTube!

I can imagine a world in the not-too-distant future where all human activity will be carried out on YouTube. Stay with me on this one. We'll watch entertainment videos there, play music, video-games, use it to communicate, eat, breath, dance the horizontal tango. Everything.

It'll be like the Matrix except it'll be full of 14 year-old vloggers decrying their lot in life, and fat people who can't leave the house taking the Pizza Roll Challenge who taste of heart attacks and diabetes. I can't wait.

So, want to know how to win this glorious prize? Have you got 5 minutes to spare? Then go wrestle a crocodile while wearing a three-piece suit made of rotting meat. Then once you've done this mail us the head of the croc and we'll send you an iPod Touch. Easy.

Of course, I'm joking. It's a shark you need to wrestle. Aha! No, if you have 5 minutes to spare, which I'm sure you have seeing as you're on this site, click here and fill in the Kontraband survey for all budding ninjas and ninjettes; telling us your thoughts, what you like to watch and what you think of the site.

Don't hold back now. And don't worry, you won't be spammed by a Nigerian asking you to advance various sums of money so you can eventually become rich beyond your wildest dreams. Promise.
