My rat likes to gnaw on the stems. She's cool like that. On a side note, welshsmoker, you might get a kick out of this, I named her Keir (Gaelic for "Black" or "Little dark one").
I like Dam's Metroid one (my son called the name) and Beansleys (not sure WTF it is but it's mesmerizing). I did mine; Photoshopped the black and white pic, and set the copy. If I had a dollar for every Pink Floyd tune I've listened to while stoned, I'd be rich.
