About a year ago I found a useful website (about 500 upvotes when I browsed) when browsing https://news.ycombinator.com/best, I didn't use bookmarks to save it, I also tried to use hntoplinks to find, but did not find, I hope you can help me:
The home page of the website consists of several grids, each grid uses several simple graphics to explain a thinking mode or problem solving structure, there are about 25 modes in total.
Thank you for helping :D
