Cute Plant

I don't often find myself applying the word 'cute' to flora, but I do feel this one qualifies.

I don't know what it is though. Not sure what I could google to find out. 'Cute pink wall plant looks a bit like a bunch of grapes'?

Edit: I've been informed that this plant falls under Sempervivum, a genus of flowering plants which commonly store water in their thick leaves, allowing them to live happily on rocks and such.
