    That’s actually quite freaky. I wonder if commercials will start advertising this and create a buzz among it’s viewers.

    I found a program that works better than coagula, it’s called AudioPaint, you can find it here:
    Just Make Sure That, In The Audio Settings, You Set Interpolation & Scale To Linear.
    Also (If The Picture Is Gray-Scale) Set The Left Channel To Brightness, And The Right Channel To None.
