Main features: Live Wallpaper, desktop Widget and Memory game. The app contains a Gallery with previous images too. This is an archive of images received in the past. Put an image from your favourite feed on your desktop or play a Memory game with images from the feed.
Possible sources include: Someecards, 9GAG, Webfail, several kinds of (funny) animal pictures and other pictures of nature, funny quotes, National Geographic, Wikipedia picture of the day, Аткрытка / Atkritka, IQkartka for the Polish people, and for the dutch people: Fokke en Sukke. But maybe more interesting is that you can use the feed of a user at Pinterest, twitpic, Instagram or even a Facebook page as source.
