Thanks to @chrispirillo for exposing me to RjDj again. This iPhone app takes ambient sound and based on the theme that you select, turns into different types of music. Sound weird? I did too and and had no intention of picking it up until I saw the video link that Chris posted up on his blog.
Check out the video below and then links to the free and $2.99 version of the RjDj applications, the latter of which includes multiple themes (scenes in RjDj talk).iPhone App Store - Free versioniPhone App Store - $2.99 versionAHA.
