QVJ

Quantum VJ - is an 8-bit glitch style electronic pendant, audio visualiser and video generator. You can connect any sound source to this device via a mini-jack (synthesizer, player) or pick up external sound on the built-in microphone ( random conversations, wind or music). It can also visualise some electromagnetic interference. There are 9 display modes that can be switched with a button. This is a great pendant decoration for techno parties.
