I did this image as a funny finale. I found the background Einstein image using
google image search... I may have been a bit naughty using it and assuming it is
a public domain image. If it's not, and the background image copyright owner
wishes this image to be gone.... just say the word. The background image was only
800 x 600 so the final image was limited to this size. All I did was clean off the
equations and added Polina after I'd edited the image to give it a chalk drawn look.
