Thanks for the screenshot for my part, I just use Nspire_emu -> CamStudio -> Virtual Dub.

All-calcs then and only demos that got presented on Omnimaga, because there are too many yolo-worthy ASM demos for the z80 and 68k line out there

But in fact, not only demos, but also animations, why not ? For example we could take Yeong's old Axe rotating room, Grammer oval rotation, leafy's explosion, some scenes from The Cutting Edge of Axe and more for z80, and Lionel Debroux's fire, dissolve and parallax scrolling effects, my plasma, the above wormhole and Spenceboy98's tunnel for Nspire

Well done Matrefeytontias. Looks like this came out quite nicely.

There are also some cool water demos that have been shown on omnimaga.

You might be able to find some via Google by searching for cellular automata, water physics or maybe just water, although for some reasons, in the past 3 weeks, Google seems to miss several results and returns more and more unrelated ones.

I considered including Mode 7 and the flaming cube from your demo program, but not the 3D stars animation due to the text. I know some Youtubers will just constantly comment saying that my video is called The Cutting Edge of Axe in its entirety, even if it's the case. As for the other stuff you mentionned I would probably need to find them first, though.

And yeah not just demos might be included. For example, I might include Tinycraft and the raycaster you made (using different textures).
