@Rob Meek: Thank you very much for the special mention.

@Goatmeal: Thank you for your comment. I was always fascinated by the simple world of pixels, cubes, isometric projection. I thought about this project  - making a set of isometric dingbats - years ago, as a supplement to my isometric fonts. I opted for a 3x3x3 cubic space. There were so many possible variations, I had to cut down their numbers. The spacing between glyphs matches the white gaps within them. A few symmetry pairs are placed on caps/lower case pairs of the same letters.

@laynecon: Thank you for the compliment. For the concept, the credit should go to someone else. To tell you the truth, I've seen a very similar poster having these 3D crosses arranged in the same way a long time ago. Perhaps, it was on Shutterstock.com, I'm not sure. I could not find it again. I had to recreate the pattern by trial and error. 

More fun...

Thank you for your comments. Yeah, I was having fun with these voxels, and made a few demos to share. The GIF animation above looked like bits of data travelling on the internet, passing though hubs. Or, I can imagine the giant warehouse of Amazon.com processing millions orders with the help of robots would look very similar.

@elmoyenique: I'm very glad you shared this with your students. More fun to them. You never know, some of them might be the next Picasso.

@thalamic: Thank you for your kind words. Inspiration and amazement is mutual. Some of your works (eg. Permutation and Etched series) made a great impression on me, and pushed me to explore patterns. Lately, I'm thinking about a font based on islamic patterns. It won't be easy.

@yellowdoor: I'm sorry for the late reply, somehow I've missed this comment. However, I've made the glyph for you. It's an interesting one: three steps carved out of the visible half of the cube. I wonder, how does the other side look like? Perhaps, there are five small cubes cut out from the other side too, so as to maintain balance and symmetry.
