I have seen art that has blown my mind and I remember most of the work but I cannot tell you who did it as it has been years since I have been in a great gallery.

I'm a big fan of H.R.Giger, and M.C. escher.

Also have you heard of Fat Cat Art? She photoshops her cat into famous art. Hilarious

I love William Bouguereau, he's amazing

I love Impressionist art.

Magritte (The Empire of Light, particularly), Picasso, Keith Haring, Caravaggio, Whistler, Van Gogh, Renoir, Degas, Sisley, Toulouse-Lautrec, Ed Clark, Elizabeth Murray, Sigmar Polke, Manet, Monet... Where do I stop? Love the great museums, and the small ones. My faves are The Getty, MOMA, the Guggenheim, the Metropolitan Museum of Art (could lose myself for hours at the Temple of Dendur)... So much art, so many eras, so little time.
