When I was little, I would spend hours lining up Legos on their ends and creating elaborate tracks through Tinker Toy constructs and Lincoln Log villages filled with Playschool people and stuffed animals. I called it "Tippyland" and my parents enjoyed the long quiets until I pestered them to come view my creation where I would magnanimously tip the first Lego over and watch the hypnotic domino-effects of a hundred or so Legos falling in rapid patterns.
I love this stuff.
Hence, my latest offering: the Rube Goldberg-like official video of Ok Go's This Too Shall Pass. Too fun not to share! Enjoy!
