Hi! I'm Daniel, one of the developers at Trello.
Not quite two years later, Trello had its 5 millionth signup and I thought it'd be fun to keep with tradition and hide another little game in our announcement.
For years I've been hearing comments about how Trello kind of looks like a game, if you stand far away and squint your eyes a little bit. Taco Out! is a game2 that kind of looks like a productivity application … Trello!
So enjoy! And don't forget to get back to your actual cards; Trello is supposed to help you be more productive!
