First Double Sided Board Lives!

Some time ago I purchased the Pulsar system for making printed circuit boards. Since then I've made a number of simple single sided boards then felt ready for something more complex. This is the result. Design wise it's a straightforward Charlieplex display for 9 outputs. The driver holds a 16F688 pic microcontroller. Currently the software is just running a simple test program, but it's implemented with a library that allows me to address individual pixels. I plan to use the 688's uart to stream animation to the display, along with playing animation from ram or eeprom.

Here's a still of the display and the driver unplugged - the driver is pretty light weight.
