Thanks Simon. Ouch! Mr. Cornwell clearly didn't understand spacefilling, and promulgated misconceptions. Points are not pixels! Filling space with countably many line segments?? Don't get me started. Off topic: In case you haven't noticed, Mozart is back. <https://www.youtube.com/watch?v=ViXQjQWXZ88&list=PL-Gn370E2twVQznmK96rG6bibdshqiTJm&index=20> Seriously <https://www.youtube.com/watch?v=DugNH4EeDeQ&list=PL-Gn370E2twVQznmK96rG6bibdshqiTJm&index=2>. Haydn <https://www.youtube.com/watch?v=eyCtwIYYv5U>, Bessonov <https://www.youtube.com/watch?v=bXMRoM18gjo&t=7m28s> He wrote these three little holiday tunes. https://www.youtube.com/watch?v=UnIHwJu2ArQ&list=PL-Gn370E2twVQznmK96rG6bibd... https://www.youtube.com/watch?v=TME16gN21G8 Just Google up Елисей Мысин and enjoy. The tall kid in the duet is his great friend Иван Бессонов, who is now famous, and eight years ago was a lot like Мысин is now. —rwg PS: https://www.youtube.com/watch?v=fUzBl_yayTo (Good luck with your Youtube ad blocker) On Mon, Jan 4, 2021 at 9:17 PM Simon Plouffe <simon.plouffe@gmail.com> wrote:

Hello mr Gosper,

I think you will find this of interest, https://vimeo.com/98285334

these are films made in or around 1976 with a tektronik screen, with dragon curves, triangles and such.

They were made by a certain Eric Cornwell, and some other Cornwell in the same family I presume.

Best regards, Simon Plouffe ps : happy new year.
