Canadian Jensen Kimmitt took home the the title in the "Single A – One Handed String Trick" division at the 2010 World YoYo Contest over the weekend, and this video of his performance is exactly the sort of thing you'd want to watch on a Monday morning:
Confession: I have never been able to work a YoYo in even the most rudimentary way. (After years of not getting it, I gave up trying at around twelve.) I'm sure there are some interesting physics involved, but to me it always felt like a game of "drop object," which is frankly much more fun when breakable materials are involved. So if you could even get the damn thing to come back up, you were pretty impressive in my eyes.
All of this is to say that Kimmitt's accomplishment here is basically magic to me. So, congratulations on your win, Mr. Wizard! (And nice music choice, as well.)
