Our beautiful mural was done by artist David Rock who is known around the world for painting gallery backgrounds for aquariums, zoos and museums. You probably are not aware of it, but if you have visited Disney's Animal Kingdom, Chicago's Shedd Aquarium or the Central Park Zoo you have seen more of his work. Here is a link to his website so you can see some of the other scenes he has created: http://home.att.net/~davidrockstudios/ We are very careful with the mural, but the birds are not. When was the last time you paid attention to a gentoo's tail? They are members of the brush tailed penguin family and have very long, stiff tails which assists them as prop for balance while resting on land, a rudder while in the water, and as I have found out, at times little slings. You see I noticed right away tiny white specks on the mural. I discovered that every time a gentoo wiggles it’s tail...which is a lot....they ever so delicately fling guano on the mural. So you may see myself or others in the back of the exhibit delicately dabbing the mural clean. It’s a balancing act between cleaning poo and not wiping away any of David’s work. His brushes are much more artistic than the brushy tails of the penguins.
