Avoision is a site that has lots to offer your inner geek. I don’t know if it’s one guy running the site or a group, but there are a ton of really interesting projects that they’ve done. There are things such as Flickr-Generated poems, random text generation, and a music program that plays notes based off of the numbers in Pi. Don’t worry, this site isn’t as nerdy as it sounds, and there really is a lot of fun stuff to look at.
