The heads up display is very cool. It works really well at night but it gets washed out during the day. I've got a hardware mirroring display which corrects for the reflection in the windshield but what I need is a piece of reflective window tint on the windshield where there virtual image appears. The tinting will serve two purposes: 1) It will make the display more visible during the day and 2) It will remove the double image created by reflecting off both the first and second surfaces of the windshield glass.
This whole project is really a version 1.0 release. Many of the systems are cool in principle but need some tweeking in their application. Most of it does really do what it's supposed to though which is quite cool.
: HUGE display(LCD monitor) though.. beware of the cops. =)
