It does indeed work! You can see it running here on my +3 in my "retro cave" :) https://share.markround.com/sphere.jpg https://share.markround.com/sphere.jpg I have also uploaded it to my TNFS site[1], which you can also access through an emulated Speccy in a browser (or a real Spectrum if you have a Spectranet/Spectranext card fitted): https://jsspeccy.markround.com https://jsspeccy.markround.com Press option 4 on the main menu when it loads for recent uploads. It's really cool and very, very smooth. I wasn't quite sure what to categorise it as on my site, so I filed it under "demos" as I think it's a very impressive bit of code :) Thanks for sharing! -Mark [1]=More details at https://tnfs.markround.com https://tnfs.markround.com or on my "DevOps for the Sinclair Spectrum" series of articles which are linked from both sites.
