A definite pattern. The first Great Seal still sits on the wall next to Washington's pew at St Paul's Chapel on Broadway in NYC (the same church used a control area for cops and firemen during the 9-11 attack). That seal has the stars disbursed. It seems there was a design here--and it does look like the Star of David. Washington was very thankful for the support of the small colonial Jewish community (3,300 people out of about 2.5 million total) whom (essentially) all were patriots.
What about the main Catholic Cathedral in Bremen, Germany? What's up with that design in the brick? Was this a synagogue once? (Picture is click-able to see a bigger image).
