A new browser instrument called Pixelsynth allows you to create music using a library of pre-selected images or uploads of your own – with interesting results. Created by US coder Olivia Jack, Pixelsynth’s scrolling cursor rolls its way across a monochrome image and plays notes when it comes into contact with a light-coloured pixel. Every song has a spectrogram that can be derived from it, and conversely, any image can be plugged into a spectrogram to create a series of sounds to go along with it. Essentially, all images sound like something. Hours of fun.
