XDA member antru has developed a very cool app for Windows Mobile. The app is a 3D task manager that is comparable to switching between active windows on Windows 7 or Vista. The app allows you to flick through running windows and open them with a single tap. It runs very fast as shown in the video and is still experimental.
You must have WM >= 5.0 to run it and hardware accelerated 3D Graphics. It uses 1 MB per window task also. The list of currently tested devices is:
1. HTC Max 4G
2. HTC Touch Diamond (to slow yet)
3. HTC Touch HD
4. Dell Axim x51v
5. Sony Ericsson XPERIA X2
If you would like to contribute and try it out yourself, feel free to join the discussion thread and download it. Report your feedback and bug reports to the developer as usual!_________
