Drawing 3D sprites in screencoords?

How do I draw "2D" in screen coordinates using 3D objects.
The reason I want to do this is that I want real alpha blending in my GUI. (So just quads with texture+alpha blending really)

I can see that I can project a 3D object onto the 2D screen but that's not exactly what I'm after :)

Thanks in advance

There are a few code archive entries including... 2D_TO_3D

Ahh thanks. Curse the disabled search function :)

Yes yes. I got it now. No need to rub it in ;)
