Unfortunately at the moment i can only get it to work with Chrome. The button doesn't show up in Firefox or IE at all for me. That wouldn't be too bad, except that i can't get featured videos to play in Chrome, it just sits on a black screen forever because it can't figure out it needs to play the commercial first. (The owners of Chrome really ought to sit down with the owners of YouTube and work this out.)
But here's a (non-featured version) of Wake Up Cat. If you've never seen it before then you should watch the original before turning on 1911 mode. It almost seems like the cat is dancing in time to the music.
For another strangely appropriate video for 1911 mode, see the 1980's Firefly Intro :)
Also also, My Apocalypse Pony :)
(Also already updated based either on GMT or east coast time, ThinkGeek has their usual cool stuff.)
Edit: Also, VGCats, i think the funniest part is actually that he's down to a comic every couple months, but was able to pull something off for this :)
I'm now looking at this list of sites, so i should probably stop pestering everyone about individual cases :)
Edit edit: Okay, i lied, cause coraa totally needs to check this Minecraft link out since she just started playing :)
