Lets Create! Pottery - this does work on the Xoom but you have to be patient - 
- you can't start the app if you're in landscape, just immediately crashes (once you have the app started, turning your xoom has no effect and won't make it crash. 
- when you start if  it hangs on the initial splashscreen from the developer - hit home then restart the app and it will start. 
- when you're finished creating your pot, the screen will freeze showing your pot shaking back and forth - press home, restart the app, and your pot will be ready to go filed under "My Creations"  from there you can sell it or share it or whatever. 
-- also just noticed that sharing doesn't work.  I tried facebook and email and both did nothing.  didn't try the developers website share thingy because I didn't want to go through the hassle of creating an account. 
Hopefully they'll get this fixed because when its working, it really looks great on the Xoom.
