Holiday Amusement with Simple Arduino Circuits

I had some spare time over the holidays, and decided to break out an Arduino that I had been sitting on for over a year.  Since this was my first time playing with the microcontroller, I decided to start with some very simple LED cirtuits and programs.

For example, here's one where there are 2 LEDs on the breadboard, one standard blue LED and one RGB LED.
