DU-QVJ is a glitch-style 8-bit pendant and audio visualizer. Any audio source can be connected to this device through the jack plug (3.5mm). It also can visualize some electromagnetic interference and the "soul modulations" of the owner when the audio ports are not connected. There are nine display modes that can be switched by the button.
This is the coolest little custom piece of a/v hardware from the heroic and enduring @detund, a.k.a. Detroit Underground. Read the description above - it's a low-res music and soul visualizer on a pendant! And for an incredibly reasonable price. Check it out in action:
