After digging around in Telerik's old Visual Source-Safe server, I found a long-forgotten prototype of a RadMenu skin.
I felt the urge to disclose it to you, and hope that you will like it.

On second thought, this initial draft looks good enough, so we might switch to hardware production. Don't be evil, we were first! Maybe we could even go 3G...
Ok now, getting serious - you could use this sort of menu for navigating when there is a large hierarchy in the site navigation (or, to be more specific, a hierarchy that has a wide tree). Currently, no scrolling is implemented - don't flood me with comments after you touched your LCD and the menu items didn't move.
For the techies: go ahead, download the project and play a bit with it. Most of the client-side logic of the actual RadMenu has been replaced, as this is a completely different concept of using it - read this as "external skin and event overrides".

(We didn't register the telerik phone as one because there actually is a product called a "telePhone" - go figure.)
