Are there any letters or symbols anywhere, maybe on the bottom? I tried to cheat and used Google Goggles on my iPhone to take a picture of the screen image, but that didn't work -- if you have a phone with Google Goggles (iPhone or Android), you might have more luck.

Might be Gyantse Kumbum - She has 4 heads and eight arms and has other versions as well. Many of these Deities have various versions.
