I recently released
Calm. It's a small experience about steering a cloud, looking at backgrounds and listening to music. This was really my first go at developing for Android and it was also a long time since I developed anything in Unity. It was thus a project with a lot of trial and error - on the other hand that seems to be the case with most projects =) All in all things turned out quite well though.
You can find some more info on my homepage:
http://www.mansbilling.com/?page_id=759. There are two versions, on free with ads and another one for the price of about 0.99 $ (and with additional backgrounds). You can find them both here:

And note that because I've used Unity this application won't run on all devices (and in that case it shouldn't even show up in the marketplace).
