Musical Christmas Reindeer

This PCB uses an Arduino Nano as a microcontoler and has three buttons, which allow the user to choose one of three songs available in the source code: deck the halls, jingle bells and silent night. Since this PCB was developed for the Julialabs PCB Challenge, I wanted do to something very artistic, and got very happy with the result. The PCB is amazingly cut, and the cuts "inside" the PCB are very well made and gave the PCB an wonderful effect, specially to work as a Christmas decoration. The thickness of the PCB was perfect for this application, since the PCB ended up begin very robust. I've ordered other PCBs with different thicknesses to test and I liked this one more.
