Gee, and I *liked* the idea of the orca *because* of the claim that it fed on penguins :-) Oh well. (Keiko is living in Iceland now; an *amazing* transport-by-aircraft effort... just think about the physics...) I haven't heard any comments on the "saddle" idea (picture a [linux]-penguin riding a [gnu]-gnu, what "brings them together"?) but the puzzle and beehive both seem sufficiently evocative...
