Be the Bird
Flap your arms to play Flappy Bird clones. This is a Chrome extension that lets you play multiple versions of the game by flapping your arms.
After the rise (and disappearance) of Flappy Bird, a number of online Flappy Bird clones popped up. They're great, but all of them are missing a key feature - the ability to be the bird, and flap your arms to flap around pipes. With this extension, you can use your webcam and flap your arms to play 3 different online Flappy Bird clones around the web. It works for Flap MMO, Flappy Bert, and VladiBear.
