The Printed Circuit Board (PCB)

I finished the schematic capture and PCB layout about a week ago and finally my PCB is being manufactured! I did the design using Altium Designer. It's an easy to use tool that is almost as powerful as the industry leader, Cadence. It also costs much much less than Cadence. The quote for my PCB came in at $650 for two boards on a 10 day build schedule. The component cost came in at about $200, but I am reusing some parts from previous projects like the GM862 and some SD memory cards. You can enjoy some PCB pron below and I'll be sure to take pictures during the assembly of the real board when it comes in. Does this circular shape allude to some devious plan that I have for my payload capsule?
