Dan Gregor

Aka Initi is one of zestful pioneers of mapping in the Czech Republic (he tampered with the exterior of the Hybernia theatre recently) and perhaps you know his streetart stuff from the streets of Prague. As VJ he uses quartz composser. He collaborates with a local musician Sonority and also with theatre groups, in addition he is a member of Macula.
