Sonogram

Every bright pixel becomes a sine wave at that pitch, for that moment. Paint a melody, draw straight note lines, stamp a word and hear what a word sounds like, or drop any image onto the canvas. While you paint, the pitch under the brush plays so you can draw by ear. Your work autosaves in this browser.
