Hit the rapids with Google's latest Olympic doodle

It's time to pound the arrow keys again for Mountain View's latest Olympic doodle game, a whitewater slalom canoe challenge.

Our intrepid web paddlers managed a time of 18 seconds so far, and you can post your own time in the comments below -- if you dare.
