First, humans see horizontally, so a horizontally-oriented picture is what we usually prefer.
Second, 35mm film evolved from movie films at the time, and those happened to have a 24x36mm recording surface. Most digital SLRs evolved from 35mm SLRs, so they kept the 3:2 ratio, Olympus being the exception since they like 4:3 for some reason.

Medium format films come in all sorts of sizes, both rectangular and square, since it was intended for photographic purposes from the start.

Actually, 35mm movie film originally had 24×18 frames, as it was shot across the film, not along the film.

Framing and/or matting has had all kinds of shapes. Oval was popular for a long time.

and Neil, as far as making hexagonal frames goes, one the framer has set his jig to 30°, the rest is easy.

And looking at the other side of the coin, has anyone considered the difficulties that would be involved in grinding glass for true rectangular lenses?

Ovaltine: from ovum, Latin for "egg", and malt, originally its main ingredients.
