Google has a new doodle. And it's incredibly addictive.
The Olympic-themed logo features the 110m hurdles, in honour of the athletics event taking place at the Stratford Olympic Park on Tuesday.
But instead of just a static image, the new doodle takes the form of a retro-inspired sprinting game which is sure to have you hammering at your keyboard.
All you have to do is press left and right (very fast) to run, and space to jump the hurdles.
But the fun comes in finding your exact time - and bragging about your best efforts.
So how quick can you run the course? We managed 11.9s so far - but we're sure someone out there can do better. Pics or it didn't happen, OK?
