I hadn't looked at the design of the star on the Urban Outfitters T-shirt that got the ADL all hot and bothered closely, but it is actually a nifty design showing three planes intersecting in 3D space, angled so it looks like a six-pointed star.
So I decided to make a true 3D version as a Yom Ha'Atzmaut poster:
I like how it came out, so I added the 3D flag as a section in my Printfection store. You can now buy T-shirts, mugs, mousepads and similar items with this design - just go here!
