Comment 8 for bug 1447499

Bartosz, thanks for drawing those icons!

I think it's probably not the best idea to use a device shape in this icon at all, though, for two reasons. First, as Charles mentioned, it leaves very little room for showing the current state. And second, it doesn't match the curvature or the aspect ratio of the actual hardware (not even allowing for cartoon-style distortion), especially when Ubuntu starts shipping on tablets (which are usually much wider, and which don't have such big bottom margins).

My original suggestion was a keyhole inside a 3/4-circle arrow. <https://wiki.ubuntu.com/StatusBar#rotation-lock> Maybe a keyhole wouldn't work at that size, but at least I doubt it would have the problem of implying the opposite of what it meant.

I suggest that the icon be based on a 3/4-circle arrow, either with the keyhole inside, or with a diagonal slash crossing it.
