In hindsight actually I’d probably have put a little more of the computation side in the video. Based on comments I’ve received I think a good portion of the audience is just looking to get something working and doesn’t necessarily want to understand what a matrix is to get there. I think this article is a great resource for that.
Totally fair! I do think it leads people down a more interesting path though, transform matrices and processing big bitmaps lead folks to shaders! Though a DIY-with-a-scripting-language-and-iteration would definitely be a fun follow up video if you ever feel like it!

It’s worth a watch! I personally prefer Jordan’s approach, which is more focused on the math than computation.
