That's very cool! I thought my browser was glitching out when it decided to scroll out by itself but that was normal. Click the glove again and everything gets brought back!
I know they have something like that for sonic, just type in "Sonic the Hedgehog character" (you cant just type in 'sonic the hedgehog' because the new movie will come up instead) and if you click on Sonic multiple times he transforms into Super Sonic. Or if you wait long enough he'll do his idle animation too
I just tried it, it's always cute how google adds little easter eggs like this. I know there's a few other things you can search and it makes google do strange and interesting things-- like googling atari breakout and go over to images, you can play atari breakout in the search engine.
