Micro-Controller Projects for W123

[Jhu805]

Has anyone done cool micro-controller projects with their old W123's?
I have an Arduino laying around and would love to integrate it into the car somehow.

Some things I was thinking about:
- Nighttime HUD (since the dash illumination is notoriously dim)
- Back-up distance beeper
- Clock-to-Tachometer conversion (Keeping the hour hand for time but using the
minute hand to display rpm)
- headlight aiming using stepper motors (to actuate the plastic screws on the
headlights to point them around from inside the cab)
