Using an Apple Pro speaker, I made a flashing RGB LED iPod dock for about $35.
I recommend reading the entire 'ible before starting. Also, note that the volume is control from the iPod.
It consumes minimal power in shutdown mode, and is controlled by a Teensy.
This took me ~3 days to build, and you should know how to solder pretty well before doing this project.
The enclosure looks amazing when lit, it is really fun to watch it.

Step 1: Gather Tools & Materials

Picture of Gather Tools & Materials
Soldering Iron
Hot Air gun/Hair dryer
Hot glue gun/epoxy
Drill (or dremel)
Sandpaper (fine grit)
Wire strippers

(1) Teensy 2.0
(1) Sparkfun RGB LED breakout
(1) Sparkfun Mono Audio amp breakout
(1) Apple pro speaker (You only need one speaker, not the set)
(1) Mini-USB cable (will be cut up)
(1) iPod-USB cable (also will be cut)
(1) Audio plug
(1) Push-on/Push-off button
(1) 10K ohm resistor
(1) Roll of solder
(1) Headphone foam cover (black foam circles found on old headphones, I had a few lying around.)
Assorted heat shrink 
Ribbon cable or other thin wire

Step 2: Disassemble the speaker

To open the apple pro speaker, unscrew the three screws around the rim of the speaker. Remove the speaker and cut the wires. Keep the speaker aside, and pull the thick white wire out of the speaker. Discard it. Save all three screws.

Step 3: Drill and sand the speaker

Drill a hole as large as the iPod cable into the top center of the speaker. Drill slightly fast or the plastic will crack. Then, using a thinner bit, remove all the foam/stuff from the metal hole where the wire used to come out of. Drill until you can slide 7-wire ribbon cable inside.
Remove the ribbon cable, and sand with fine grit paper until the enclosure is smooth, translucent, and will blend light well.
cool so it reacts to the music? I'd love to see a video of it in action!

Could there be any bluetooth addition to be able to control lights with custom bluetooth app too?
