I thought I saw a note somewhere when I looked briefly weeks ago that it was possible to convert images to the Xspecs 3d glasses format. I don't know what that format is; I tested my specs a month or two ago and haven't had time to experiment since.
My goal here is to convert probably a clip but maybe a full 3d film - like a modern one - for display on an Amiga 2000 with a 2gb HD that has 1.4+gb free (I made a 500gb DOS partition for CrossPC that I regret now).
I think
