Neopixel clocks are pretty common, but I have done other clocks and had the basic NPT and DST change routines down already.  Wanted to do a NeoPixel clock that used the black acrylic diffusion panel that makes the pixels look like they float in space.  Also, I don't have access to 3D or laser fabrication, so I sized it to fit an existing shadow box from an arts supply house.  The rings and 4 digit display were simply hot melt glued directly to the black acrylic panel.  I pull the existing glass panel out and just replace it with the acrylic panel.

Everything fits inside after making the connections and hooking up the power supply.

I solder all the 5V and GND connections in common, the rest of the connections are done via jumper wire and a project board.   

There is a configurable 'test mode' to see if its working without the necessity of an internet connection, but it seems to connect and set pretty fast.
