KDE's Plasma Mobile UI running on MeeGo
The KDE project has a sub-project working on an advanced mobile user interface, using Qt and QML. After receiving their Lenovo IdeaPad's at the MeeGo Conference, a group of KDE hackers set about getting it running on the multi-touch capable tablet/netbook hybrid. Dan "Leinir" Turthra Jensen says it took about three days worth of work... 'tis pretty sweet stuff. I'm really impressed with the speed of development here. The video - posted by Artur Souza - shows some interesting UI concepts, such as pulling the bottom bar further up the screen to "tip" the display over to another desktop.
