Relaxing flash games

The motion of the ocean, the birds twittering, watching a small waterfall, having a great tea with a shisha(water pipe). All these can calm a person down through all his senses. But we are living in a jungle of cement, steal, glass and silicon mostly. So in my case I definitely need some things that can give me a bit relaxation from time to time. The next games usually calm me down and give me a new perspective of life in a few seconds. All of them have the basic idea in common. A simple game principle, an almost empty screen, with just a few objects of interest and a perfect calm music in the background:

This is a game I found today. The idea of the game is to change the direction/color of the light in the direction of the (?) objects, so they make sound.

The handling of the game is easy though it takes a few seconds to figure it out.

You need to catch as many signs as possible. The yellow ones give you a multiplicator of your points and the red ones take the multiplicators away and the purple ones work as a huge vacuum cleaner :) The blue tiles are points. Basically you don't need to play at all the music in the background is exquisite! :)

Just click a spot and watch the points expand. If you touched enough points you get to the next level. Very pleasing continuous music. This is the oldest game of these three, before the fancy animations could be used. In general this can be seen as an evolution of this kind of games :)
