Very cool. In a less-artistic application, you could use this idea to print multiple sections that could be assembled to make a large pseudo-parabolic mirror for a solar concentrator. You wouldn't get telescope-quality imaging, certainly, but if all you needed was to concentrate a lot of light on a small space (for a steam generator, say) it should work fine. Congrats on the upcoming wedding!
