Lumenoise is a light pen, which turns your old CRT-TV into an audiovisual synthesizer, made by Niklas Roy.
You paint abstract geometric patterns and sounds directly onto the screen. It is a playful and performative device, as anything that you do will cause an instantaneous reflection in the gadget’s sonic and visual output.
Just watch the video below, the grey square is the position of the light pen.
So funny!!!!! this is a very good tool for making music!!!!
