I remember reading a very similar article, a few years back (4-5 years ago). The fact that text is "written" with spheres, some of the images, writing it in a business card.
Edit: googling "ray tracer on a business card" gave me this link[0] which is what I had read before.
But actually reading (and not skimming) the submitted link, gave me this paragraph:
> Sometime around September 2009, I posted a version of my program to the now-defunct ompf.org (whose demise is lamented here among other places), a web forum dedicated to the real-time raytracing community.
So that's why it sounded so familiar. Oh and the "spher-y" text was just the first image, which is also cited in the other post from 2013 that google found.

- dr_zoidberg 10y agoYes, that was the one -- I was a bit distracted and didn't notice that I didn't include the link. Can't edit my comment now.
- kens 10y agoA shout-out to my former officemate Paul Heckbert who wrote the first business card ray tracer. He also wrote a ray tracer in PostScript when we realized that the processor inside our laser printer was more powerful than the processor inside our real computer. Needless to say, the PostScript ray tracer was epically slower. https://www.cs.cmu.edu/~ph/ https://www.cs.cmu.edu/~ph/
