ettings, so it makes nice blurr, but doesn't affect close range

A quote from NeHe tutorial:
"We push the matrix (which basically saves the position of everything on the
screen) and use glScalef(1.0f,-1.0f,1.0f) to flip the object upside down
(creating a real looking reflection). Setting the y value of
glScalef({x},{y},{z}) to a negative value forces OpenG
d of "flipped",
increase eyez in glu.LookAt().
See it it works, then we can sort out the rest.

Yes, that's what I'm looking for. I boiled that program down to the up

I'm trying to render an overhead, 2D scene with the "camera" at the
