Most complex bike lighting system

Hi everybody,
I'd like to show you my current bike electric system. It's not the first system I've made but it's definitely the most complicated one. It works almost like that of a car.
It comprises 8 ICs, 20 transistors, 39 diodes, and 57 LEDs.
The main features are:
- SLA battery operated at 14.3 V supplied by the DH-3N71 hub generator (yes, it can do that!)
- 3 power levels of the front light (1 - 3 - 6.5W) in constant and strobe modes
- 5W halogen spotlight as the high beam
- front, rear and side turn signals even visible at daylight (when I use my hands too ) with acoustic indication
- 25-LED tail light with constant and blinking modes of 2 power levels (normal or fog) plus extra brake-light function
- powerful 5W horn with 11 different sounds (including a machine gun )
- accessory plug
- it's completely rain-proof

Here's some photos. Maybe they're too big - I like details. But it's not as bulky as it looks like.

The control box with the front light, the horn and all the circuitry:

I still use my old Luxeon 3W emitters. They were too expensive back in the days to think of anything else now. Besides, they still give out enough light for me.
There are 11 essential indicator LEDs on the top of the control box. From left to right: Left turn, high beam, front light status (1, +2, +3W), rear fog light, low battery, auto charging mode, manual mode (by-passing the automatic charging), over-charging (15V overvoltage protection activation in the manual mode), right turn.

Here's how it looks inside:

You can clearly see the "big" speaker (well, 2'') with one of the sound generators on the top of it.

The high-beam 5W spotlight:

The battery box:

Some schematics (sorry for that bad resolution)
http://img167.imageshack.us/img167/7416/notesuz1.jpg

All the lights in action (turn lights caught at full power, front and tail lights set at the lowest power).

With the light on, the turn lights are always shining slightly even whe they're off, they are driven at 10mA. When blinking, it's 200mA.
And now's when it's getting really crazy - there are two green LEDs that are not visible but they illuminate the ground below (I just couldn't help myself - how I love that forbidden green colour!)

Don't try this at home!

I forgot the picture of the tail light:

It's 25 very good LEDs in the housing of an old Cateye. There were so many extra lenses in the cover for only 3 LEDs! Now it's more effective... The control circuit is in a small extra box.

It doesn't weight a ton. The main parts of the weight are only the hub dynamo and the battery but I don't care anyway.

I'm jealous.

Would be cool if someone made systems like that commercially

You should make a video of a night time demonstration and post it on youtube or something. That thing looks cool.
