If you've ever wanted to have an Angry Bird fly across your watch, today's your lucky day, as the Angry Birds Aviator Watch Face is available on Android Wear.
It looks like your typical watch, but a small anger meter builds over time which, when full, triggers one of the eponymous Angry Birds to fly across the screen.
There's apparently also a special event triggered at ten past ten, when the clock hands make a frowny face. Presumably it will involve a narked, winged creature of some kind.
If that sounds like your cup of tea, you can grab the watch face for free from Google Play.
