Well, this is just impressive. YouTube user ShanesDominoez has posted this rather spectacular dominoes tribute to Nintendo that contains over 30,000 dominoes. The only problem is that amidst all the Nintendo properties (and their theme tunes!), they've thrown in Sonic The Hedgehog as well. Their justification is that they've been playing Sonic games on Nintendo consoles since the early 2000's, but I still don't know if the little blue dynamo really belongs here.
Still, it's an incredible piece of work!
