Joe made an excellent write up and created some great sample code to go along with the NeoPixel shield. This was helpful because most of the examples in the code provided by Adafruit were geared for NeoPixels in general, this one however was built with this specific shield in mind. You could use this same technique to control any type of NeoPixel component. I started with his example and modified slightly to accept commands from bluetooth rather than serial over the USB cable.
Note: I suggest you use the stacking header that comes with the neopixel shield instead of the regular ones. I ended up soldering wires on to the top of the shield in order to connect the bluetooth module.
I put mine inside of a cardboard box that was originally packaging for a toy. It already had some nice cutouts with plastic "windows". The bare LEDs are rather bright so I taped a piece of paper over the holes to diffuse the light a bit.
