Well, i still was in the university but i've had chance to play with a few ones:

LCDS, WebORB specifically and Flex 3 RoR Lift Web Framework

And in the Q4 of the year i used all my time to learn Android and a lot of cool API's:

Overlay-Manager to recognize gestures in Android AndEngine Geocoding and reverse geocoding Notifications by vibrating SMSManager

I really enjoyed developing Android stuff, and i'm keeping up with these for a while.
