Null Ventana is a free, open source lo-fi visuals generator in the spirit of the Atari Video Music and Eyesey that runs in any* browser. It includes a video mixer, effects, LFO, filters, and responds to music.
Richard loves to add ambient visuals to our videos so he created Null Ventana as a way to easily generate a wide range of patterns. It turned out to be a lot of fun to play with so we thought other people might like it too. Have fun.
