I came across an interactive digital work called OKOgame that uses NASA satellite imagery to form an audio-visual experience triggered by mouse clicks. It revolves around a target-like centre which splits into rings that you can control with your mouse. Working like a puzzle, the aim is to get them to fit seamlessly together revealing the original satellite image. There are various levels, each becoming more complicated with an increasing number of moving parts. The soundtrack is recordings taken from within space shuttles.
