Sorry, could not resist the paraphrase.
Some of you may find it useful, if you know what to do with it.

When God said “Let there be light” he surely must have meant perfectly coherent light.

Make a small transparency of it, but try to preserve the resolution of it. Expand/Up-Collimate a laser beam and shine through the Zoneplate. If you shrunk it correctly, and illuminate enough of it, you will see that it has a unique optical property. Or Google "Optical Fourier Transform" or "Diffractive Optics"
The old way would be to shrink it onto film using a enlarger. However, you'll have to settle for a 600 DPI laserjet with toner, these days. I'm not so sure its worth doing anything with a inkjet.
Enjoy,
Steve
