This is a recreation of those Old style Mac II Wallpapers but in modern high resolution. It is not an exact duplicate but it's very close. It was created at high resolution in two renderings, one for 4:3 (square) monitors and another for widescreen monitors. It was created using Blender. Actually I'm not sure if the original was a wallpaper or a picture that was used to show the Mac II color prowess but it was hard to see a brochure or photo of the Mac II not showing one of those pictures so it might bring back fond memories for some Macintosh users. In addition, I'm not sure but I think that the original image was 640 x 480 in only 256 colors dithered so it didn't look as smooth (it appears to be smooth in the Mac II photo below because in the photo the image is greatly reduced). I hope that the Mac community enjoys it.
You can download a zip file containing many resolutions from 1024 x 768 all the way to 2560 x 1600 pixels in 3 different aspect ratios 4:3, 16:10 or 16:9 from the link below. I used little compression to preserve their quality:
