Some of those folks on inscrutables have some pretty cool ideas. A few do a very good job of explaining how they did the project but most do a horrible job.
Can anyone make heads or tails of this Indestructible article?

The project is based of of a POV method similar to that used in some of the original mechanical televisions.
He mentions two versions of the clock. A simple version and one that shows numbers. But he doesn't mention anywhere in the article of how he does the numbers!
I think I have an idea. If you look closely at the one photo it shows a disk with holes. The photo is not real clear but the best I can figure is you would have a hole for each row. There would be one hole per column. The MCU would light an LED at the appropriate time. So for example if you had 8 holes and did want to show a straight line, the LED would light 8 times all with a delay between illumination to give the appearance of a straight line.
Does this sound like a plausible explanation of how it is done?
