I have been working with Flex for the past few days and surely i have to confess i think its the coolest way to develop awesome Rich-Internet-Applications !

and this is one example i have come across recently ... its a 3D arena Theater where u can make this guy to move around by clicking on to specific screens in the play area in the arena.The are different screens for a Calender,a movie player, a photo sideshow, a visual data representation etc

even this is pretty basic , but still very attractive

you have to check it out. its just amazing ... if you have worked with flex before i am sure you would really appreciate the example.
