Matthias created a X-Mas tree project using the DirtyPCB boards from dangerousprotorypes.com :
The project features an USB capable PIC16F1549 µC with:
USB FS device
48 MHz internal Oscillator
2 PWM modules
10-bit ADC with Voltage Reference
Integrated Temperature Indicator Module
The LEDs are connected to the 2 PWM outputs via N-mos drivers. A Potentiometer is connected to one ADC channel for controlling the brightness of the LEDs or possibly the speed or variation of animations. Different modes of the X-mass tree can be switched by pressing a push button.
