Hello forum! Here is my little summer coding project, an audio reactive visualizer and micro lo-fi vj app called Ljudbilden. It has 6 different scenes that reacts to sounds through the microphone or line in. It is also possible to further mangle the pixels with fx like mirror, roll, glitch, invert and film grain.
Available for download at: Ljudbilden by humbletune
Here is a video of Ljudbilden in action made by the brilliant Perplex On with music by equally fantastic electronic jazz duo Elf Traps. Love those guys! 
Cheers
