RICH SMITH  It does actually work! Funny little app - can't quite see the point in it and does mean that you're camera has to be on all time time; not good if the camera needs to be used by other applications.

However, a neat way to entertain the kids and might be the start of something which could help those unable to use a mouse or keyboard.

Worth playing around with if nothing else.
