Die Fail Whale
If you're a Twitter user you're probably familiar with the fail whale that appears every time the site is down whatever the reason is. Here's an idea, that this simple shooting game, "Die Fail Whale", had been released by Twitter and linked from that fail page so you could get rid of all the anger, instead of a "we're right back" static message.
But actually it's not from Twitter, it's been done by Andrew Conn, kudos for the good laughs i had shooting whales :)
