The kylindros

The roller — the drum, the thing that turns because turning is what a cylinder is for.

Every fragment traces a ray and solves it against the cylinder, so the foreshortening is the true cosine and the front of each slide genuinely swells toward you — a CSS deck rotates a flat plane, which is correct for a plane and therefore never bulges and has no depth at all. That depth is what the optics are built on: the turning slides recede by up to the drum's radius, so a thin-lens circle of confusion taken from the ray's own hit depth defocuses them because they are physically further away, a grazing-angle trace of the neighbouring slide smears across the curve, and chromatic aberration disperses from the optical axis the way a real lens does. Nothing is applied to the photograph's colour. The front slide is bit-identical to the source on the axis — the aberration is gated off inside its arc so it cannot creep into the corners. A cylinder is ruled along its axis, so straight lines in the photograph stay straight and buildings survive being turned. It never turns by itself.

Slot

Featured work on a home page, or one project's photographs in sequence — the three or four pieces you lead with, not the index you scan.

Budget

Three to nine photographs. Under three there is no drum to wrap; over nine each slide holds less than forty degrees of arc and none of them reads.
One per page. It is the moment, and a page with two moments has none.
Photographs only. A text slide is illegible by thirty degrees, and the optics have nothing to work on without depth in the image.
Same-origin images, or cross-origin ones served with CORS and marked crossorigin. Without it the texture cannot be uploaded and it silently drops a tier.
Never as the index. It shows a few things in sequence; a body of work that has to be scanned is pinax, and filtering it is ostrakon.
Leave `focus` under about 70 on small tiles. Shallow depth of field is the effect on a wide stage and mud at 300px.
