We have quick profiles of two companies that launched at the TechCrunch40 conference last week. Metaplace lets users build their own virtual worlds and put them on their Websites. Founder Raph Koster takes us through a demo. And Musicshake is a Korea-based service that lets users create their own music. Kihong Bae and Blue Yun do the demo, starting at about 6:00.
