The Amiga Pointer Archive is missing one: We went to get a Fast Ram upgrade for a A1000, and we looked at his work, and it was cross between a jeweler and sim-city.
We had the work done, and he put his boot disk into test it. He had the most interesting pointer... the boot disk was called Romeo, and the pointer was just a 3x3 square diamond, with a single line of pixels, to a 2x2 square diamond of pixels with a hole on the center... so you could literally see a single pixel through it. I had never seen anything like it, so I copied on my Macintosh, ( System 6.0.8, and system 7.0.1 ), and later to windows 3.1 onward to Windows XP, later screens became too large to need anything close to a single pixel pointer.
I wish I had the disk, that we got it from... just a single 3.5" Floppy labeled "Romeo" and we all knew what it was.
