The joy of looking at the Ballantine's Ale logo

200802181058Today I had a conversation that brought to mind one of my favorite logos, the three rings for Ballantine's Ale.

Call me simple and easily amused, but I never fail to be amazed by the fact that no two rings are linked to each other, yet the three as a whole are inseparable.

Wikipedia has a nice article about these rings, which are called Borromean rings.
