The first pattern was drawn.

The 1st pattern was a failure. There were gaps in the segments. 

The 2nd pattern was a failure.  There were still gaps.

Final pattern, with paint for brightness.  

Completed LED installation.

Soldering & labeling of all the LEDs.

Complete back wiring

Complete board with lots of defects.

All the ground pins had to be grounded for it to work at all.  The speaker needed a MOSFET with more power.  

1st light of the LEDs powered by the mane board.

Maximum brightness, showing the 1st time display.  Voltage had to be reduced to the minimum in order for it to be dim enough to sleep by.

Each segment was individually covered in 2 layers of wax paper.  Laser printed transparencies covered the icons.

IR sensor, speaker, mane board strapped in.  Every segment has its own ground wire to the mane board.  A 2nd voltage regulator powers the colon.  That contains 10 old LEDs which required higher voltage.
