French multimedia studio So Far So Good has just released an update to their beatbox mixing site, incredibox.fr, which allows visitors to create a cappella songs from a variety of effects, beats, melodies, choruses and voices via a simple drag and drop interface. Sounds for the project were provided my the band Incredible Polo. The site is completely free to use and, I must say, quite an entertaining time killer.

Check out the video above to see the site’s impact during a recent exhibit in Saint-Etienne.
