As an excel developer in the 90's, this brings up great memories. I wrote the Doom Excel credits in Office 95. I wish I'd had thought of doing this instead. Kudos.

My brain is desperately attempting to recall the sequence of steps to open it. Ctrl + Shift, clicking something in the Help -> About... dialog box, then F5 or something? And/or there was a star-wars scroller in one of other apps, right?

I remember the flight sim easter egg in Excel 97, that was certainly unexpected!

As a less extreme example, an implementation of the AES cipher in Excel formulas (no macros): https://www.nayuki.io/page/aes-cipher-internals-in-excel

That reminds me of when my mother-in-law asked me if you could compute IBAN check digits in Excel. The suggestion by IT had been to cut-and-paste customer data into a random "compute IBAN check digit" website, one customer at a time, because they couldn't be arsed to update the database automatically.

Could be rewrited for LibreOffice Calc?

It renders in LibreOffice - although I wasn't able to get the movement to work, even after enabling macros.

Try logging a bug, I know it might seem ridiculous but it may help with efforts to improve VBA compatibility.

Sadly LibreOffice ignores user bug reports.

Since Excel is a pure functional programming paradigm, I suppose this will make FP people happy to see FP taken so far without mixing in any imperative constructs. It's the Übermensch of functional 3d engines.

calling this a functional 3d engine is a stretch, but sure grats functional programming, you have entered the 80s

That reminds me of people doing 3-D engines in MegaZeux.

MegaZeux is a ZZT successor.

And uses ASCII characters. MegaZeux up'd the ante and allowed you to edit the VGA text glyphs so you could make "sprites."

Back-in-the-day Megazeux and ZZT were like their own dedicated systems, like software console systems. It was really fun to see what people did with incredibly constrained systems.

Hardly. Why do you say that? I have personally worked on bugs reported by end users.

That's been my experience. Bugs reported and then either ignored or closed as duplicates of ancient bugs.
