Tracing Condensation

On a cold winter night a window fogs over with condensation, and your finger is the only brush you need. Trace lines across the glass and droplets gather along your strokes, trickling down and slowly warping the picture into something eerie. What starts as a doodle drifts into horror the longer you draw. When you finish, the view pulls back into the room so you can see the window you just covered in marks, and you can save it and share it as an image. It runs right in your browser with no download, so a small winter ghost story takes only a few minutes.
