UARTSIFARTSI vs Babelia
Both projects try to hold every possible image. They pick very different rules for how to line those images up.
Babelia (Library of Babel)
Babelia, the image annex of libraryofbabel.info, enumerates every possible 640×416 image in 4,096 colors. You either request a random image or paste an address and the site renders that specific picture. The space is astronomical — roughly 4096640·416 images — and the interface is deliberately random-access: there is no meaningful “next” image.
UARTSIFARTSI
UARTSIFARTSI enumerates every black-and-white pixel image across every size in one deterministic order. An image’s address is a triple (w, h, k):
- Sort by pixel count n = w·h, ascending.
- Within an n-bucket, order the
(w, h)pairs:(1,n)first, then(n,1), then remaining factor pairs by ascending smaller side, wider-than-tall before its transpose. - Within a pair, walk k from
0to2^n − 1. Read k as an n-bit binary number;0is white,1is black.
Side by side
| Property | UARTSIFARTSI | Babelia |
|---|---|---|
| Palette | Black & white (2 colors) | 4,096 colors |
| Sizes | Every (w, h) up to 32×32 | Fixed 640×416 |
| Ordering | Total, deterministic (w, h, k) | Random access by address |
| Next / previous image | Yes — always defined | Not meaningful |
| Naming / community | Anyone can name any image | No naming layer |
| URL shape | /img/w/h/k | Opaque address string |
Which one should I use?
Use Babelia if you want a Borges-flavored plunge into a huge, high-resolution color space with no path through it. Use UARTSIFARTSI if you want a shared, walkable catalogue of every possible pixel image — with stable URLs, a next image, and names contributed by other people.
