This looks beautiful... However I just drove home with it and have a few observations.
The clock works great.
The Speedo did not work at all and there were no values in the "odometer"
The Compass works but there are some issues.
It is not pointing accuratly, seems to be off on the wriong side of north. When I turned west from due north the compas swung to the east (The numbers displayed in the "odometer" seem to be accurate).
I have been using a .swf called compass.swf. This is pretty plain but it did work.
The new compass looks much nicer and seems to move in much finer increments. On the old compas the pointer moves, on the new one the pointer stays straight ahead and the background moves. This seems much more like a real compass but it does have serious problems in a moving car. With the old one a quick glance at the pointer told you direction. With this one you need to concentrate on the letters on the background. This seems much less practical in a car.
I'm not trying to be critical, I could never build this myself, but hopefully some constructive criticism can make it even better.
