pictune.pngIcyLime's PicTune is an audio puzzle which asks players to identify shapes based on the sounds their patterns make. Players can scan the lined graph with a blue bar vertically or horizontally to listen for where notes (the shaded areas on the graph) may be. The above photo already reveals the answer to one puzzle, which makes one loud chord when scanned horizontally and one long run, a quick pause, and then a single note when scanned top to bottom.

PicTune's audio-visual tutorial does a better job explaining the mechanics than I have done. Give PicTune a try and see how many shapes you can guess.
