I've been wandering around, looking at all of your wonderful icons and just found these!!!! ESCHER!!!! (I had several of his posters on my walls all through high school and college, and smaller prints of a couple in my office for years)

If I hadn't been using my default icon for 20 years, I would totally use your Escher's hands drawing as my default.

Thank you for making all of your wonderufl icons and sharing. I've grabbed a few, and am definitely crediting.
