I like simple, clean designs that have unique, custom fonts.  Where the fonts are part of the design instead of just a canned font used with a design.  Perhaps a A Torah scroll that is emitting the light.  Or If there was a way to make it look like the words "light of Judaism" was coming out of a Torah scroll that was open instead of being from the side being head on, that might be easier and look better too. She should play with it from all angles but it must look like the words light of Judaism are coming out of the Torah scroll as light comes out of a light bulb@

I cannot think of anything Gitzart could do to improve!  Excellent!!!
