Weird things happening with Google

[Tgo01]

Sometimes when I'm on google.com the webpage will do weird things. Just now the screen started rotating clockwise before going back to normal. Another time something similar happened but I can't recall exactly what it was. Does anyone know what's happening? It's only happened a few times and it's always on google so I'm assuming it has something to do with google.com.

I use Firefox and have Windows 7. It's not a big deal just wondering if it's something on the keyboard I'm pressing to make that happen or if it's just something weird google does randomly for shits and giggles.

did you type "do a barrel roll" ?

edit: actually with predictive search enabled, you probably just have to type "do a" and it will roll.

Alright I guess I figured out what's causing it. Whenever I type in 'do' then hit the space bar the screen rotates completely around and all of the search results by default are 'Do a barrel roll.'

I guess I never realized it before because if you start a search with 'do' and type the rest of your search fast enough it doesn't do that.

Edit: Sam read my mind!
