Not sure about the green display... gotta run a search.[This message has been edited by Mister (edited 01-06-2008).]

I've been playing with the Swoosh in my Fiero and that STOP and M in the display is annoying but not terrible. I finally used some black tape and covered the M, decimal and the third digit (since it's always a 0 and I don't go over 100 MPH to see if go to a 1). When I come to a stop now you see TO. I need to make up a meaning for that..... Take Off!
They work well and are plenty bright for daylight. They also have variable brightness and night dimming. I have heard green is available but I haven't seen it. There are other green HUDs out there (VFD.)
One nice feature is that you can fine tune the reading to get it dead on. Mine matches the speedo within 1 MPH from 0 to 90 (highest I've check it).
As with all HUDs, you get a ghost image (I live with it) unless you add the film to the windshield or have HUD glass.
Finally, the optical HUDs still look much better. These cheapies don't give you the sense of distance of the optical HUDs. Unfortunately that sense of distance is the focal length of the optics and they are really deep and don't fit well in the Fiero.
There are some new LED/VFD HUDs that are GPS driven. Some are even rechargeable so all you have to do is set them on the dash and off you go (once they acquire the sats). Some even output the position via BT to use with your pocket PC GPS software.
I love having a HUD so I live with the little annoyances.[This message has been edited by TK (edited 01-06-2008).]

For those who haven't studied HUD displays, there are generally three unresolved issues that prevent inexpensive HUDs from being successful:
1) Multiple images if you use the windshield as the optical "combiner" ... one reflection off of each windshield surface ... as well as low image brightness due to the poor reflectivity of plain glass.
2) Lack of collimation in the optical system, necessary to place the virtual image at (or near) infinity.
3) Inadequate image brightness during daylight and/or inadequate dimming at night.
I am currently experimenting with an inexpensive plastic fresnel lens to provide collimation, combined with a dichroic reflector tuned to the color of the display and applied to the inside surface of the windshield. If these ideas work satisfactorily, a longer-term, more elegant, and probably more expensive solution would be a single thin dichroic aspheric concave reflector applied to the windshield. Use of a dichroic reflector automatically limits you to a single-color display, but multi-color isn't really desirable in this application. You want to use a HUD to present only a limited selection of the most important and rapidly changing data, and a single color is just fine for that.
Advances in consumer display technology will certainly solve the brightness issue eventually, although at this point I still don't know whether I can get a DLP display array to fit into the Fiero dash or not.  [This message has been edited by Marvin McInnis (edited 01-07-2008).]

All true. what bothers me most is the fact that the image (in my case) is not at the focal point of infinity.
Thanks for the info, please keep us posted on any progress or updates.

Lol, how would it not fit? Thats a amazingly good Idea.

The Defi VSD Basis is a nice unit too. About $150 new. [This message has been edited by TK (edited 01-08-2008).]

The cost of admission for the DLP evaluation and engineering development kit from Texas Instruments is $10,000. Additional DLP modules for experimental or prototype purposes are $2700 each.

Which is why you either go about it another way or forget about it.
