The first is Paint Park, a simple art application. Sony explains a program which allows users to "doodle, sketch and scribble quickly and easily with the virtual markers and on-screen color palette." The Vita's cameras can be used to import imagery to paint over and around, and Paint Park also supports "online multiplayer" (ad-hoc) that allows you to share your work with friends. Paint Park will be available this week on PlayStation Network.

Next up is Treasure Park, an interesting-looking application "that allows you to create your own puzzles to challenge your friends with." The app will use your 3G connection to find puzzles to play, and you can also share your own via Near. Treasure Park is due out this summer.

Finally, Wake-Up Club is "an application [that] turns your PS Vita into an alarm clock that can sync up with other PS Vita users who set their alarm for the same time." It will also be available this summer.
