Christmas PCB - 2014 Edition

So last year I made a Christmas Ornament - figured I'd do something again this year.  It's an MSP430 powered Christmas tree!  It uses 2 PCBs that slide together.  There is a button and a motion sensor (cheap spring-based motion sensor).  It uses 12 leds - broken into two sets of 6 that are charlieplexed (so 6 pins total used).  

I managed to score some cheap MSP430G2152's off of Newark for $0.50 each (although the $5 shipping cut into it a bit), but the 10 trees cost well over $100 in total (including $25 shipping to get them here before Christmas).  

For those interested, gerbers and eagle files are attached.  I'll post some code as well - it's just very basic right now.

Quick video (might put up a nicer one later)

It turned out so great - I actually got my wife to solder one!
