Imitation is the most sincere form of flattery - and hey, even Palm admits it, in their letter to the "Palm Pre Android Theme" developer. Borrowing icons and wallpaper from the webOS interface, it looks quite similar to the interface found on the Palm Pre - and Palm's not happy. The company sent a "cease and desist" attorney-speak letter stating that the developer was infringing on the Palm name, interface, and other graphics and trademark infringements, and ordered them to remove said items by a date removed from the leaked letter. We're guessing it's sooner rather than later.
"We request that you immediately cease distributing the Palm Pre Android Theme application and cease using the Palm Pre Android Theme name and any other Palm or Palm Pre-based product names. We also demand that you immediately remove the application and any advertisements regarding the application from any website on which they appear."
