7-Segment LED Shift Register detail

While building another 7-Segment LED display for a project I took some photos.  I've been asked by some for more detail on how those things are build and chained together.  This is the same style display I used in the Game of Life display from an earlier post.   These modules are assembled each with a 74HC595 shift register glued to the back "dead bug" style.  Each segment is driven by a output bit thru a resistor.   It makes for a very simple static (no scanning or multiplexing) display and very simply programming in the microprocessor.   I really have to make a circuit board for this!  Displays by the inch anyone?
