Over on Yochai Gal's lovely NSR discord server some folks (including your's truly) tried there hand at the Gygax 75 challenge during the month of June.
The opportunity to so this alongside a bunch of other people who would regularly check in on each other was great, as in the weeks prior I had attempted several procedures to make a classic dungeon, all with lack luster results (which just goes to show that different methods will work for different people, as these were perfectly functional procedures).
As I've had a blast doing this challenge (way more than I expected to) I feel like sharing the results, despite being over a month late.
You can download the challenge for free over here.
