You should have plenty to do with some imagination. Draw a picture, write a story, (or do both and make an erogame ^^), write some music, play some sports, explore a part of the city you've never been to, invent something with random things lying around your house (someone made a 3D scanner with a digital camera, a laser level, and a record player for example (never mind photocopying your ass, you can send your friends a 3D model of your ass in excruciating detail)), learn a new language, etc., etc.
