There is no originality at all in this, but as part of a quick experiment, I’ve taken a stereo card from the 19th century, and turned it into an animated GIF. I really like the effect. It looks very much like a photo in three dimensions. And seeing as how it’s the Fourth of July and all, the stereo card I cut up is both taken by a famous American, and of a famous American.
So without further ado: Walt Whitman, by Matthew Brady.
The file turned out to be a tiny bit large. And for that I am very, very sorry.
