I regularly take inspiration for my carving from my own photographs, and often take pics specifically for the purpose of carving them. (My current oval sig-stamp is a good example of this.) Below is a photo of a mosaic that Herod commissioned so many hundreds of years ago; you can see it for yourself if you visit Masada, near the Dead Sea, Israel.
Here's my interpretation of the beautiful tile work.
