I think they used a Matel computer to do the ray tracing... No coma or
astigmatism. Lots of diffraction. Tons of diffraction. Hell, it's all
diffraction. You get the rays that make it through without hitting the wall.

And still looks like a pinhole image!

I want a multicoated T* pinhole lens cap.
