Well, he's my close friend and reblogged that post, but the post is mine. I wrote a follow-up to it, at madeofmetaphors.com, though haven't written in eons...

Thanks for clarifying. I was very confused because I follow Tynan and this did not at all seem to correspond with his background. :-) Edit--Oh, I see you listed as the author at the top. Just unususal that it doesn't say "guest post" or the like.

I found it at https://madeofmetaphors.com/shapes but blog seems a bit broken (cdn.sett.com issues I guess)

Ugh he migrated sett a while back and I bet I was doing some bad hardcoding somewhere. Hmm, maybe I'll make some time to try and fix it up. Thanks for letting me know!

Thank you for the posts. Do you write / post anywhere else publicly at all now? These were interesting perspectives.

Yeah, almost 20 years ago.
