Clearly, this app is not a game, but quite a useful pastime. With the soothing background music you can delve into the wonderful caused by touching the touch screen with one or more fingers shapes and patterns. This is very relaxing and at least a little creative.
The display on the screen is just great and constant source of delight. I could spend hours occupy myself with it and constantly design new patterns. For me a great app that deserves 5 stars.
