OddHoof

Draw any creature and it comes to life on wobbly legs to race, row, jump and dive against computer rivals.

What you doDoodle a horse (or anything else), name it, and watch it stagger down the 100m track while you tap Space to cheer it on. Five events: the race, wave rowing, the long jump, a mixed challenge and a splash dive, with a leaderboard and ghost replays of other people's runs. Works with a mouse or on a phone.
