From Jimi Hendrix to Rihanna in 4 steps

this is a web app that lets you find connections between artists based on a wide range of artist relations. It is like The Oracle of Bacon for music. Discovering the path between two artists is fun but it's a pity that the sample player doesn't always play the right songs.

Gnod helps you find things you like (but don't know yet)

Gnod is my experiment in the field of artificial intelligence. Its a self-adapting system, living on this server and 'talking' to everyone who comes along. Gnods intention is to learn about the outer world and to learn 'understanding' its visitors. This enables gnod to share all its wisdom with you in an intuitive and efficient way. You might call it a search-engine to find things you don't know about.
