I found this on xda devs and its a function picture flow demo. It's still an early build but what this will lead to is CoverFlow like programs for launching music.
I think it would be interesting to see this built into sometype of application launcher where you could slide through your applications by icon.
Anways here's the link and the zip file.
Instructions:
-Unzip files to a folder containing pictures.
-Run the .exe
-Enjoy
NOTE: There is no close application button so if you dont have a hardware key set to close or minimize get ready for a reset.
