Do you know allposters.com? It's a pretty big online shop offering about 1.3 million posters, art prints, etc... Now, browsing this huge collection is usally done, either by searching for a keyword (like "van gogh") or by selecting categories (like art genres, year, etc...). Usually, when you know what you are looking for (i.e. a Pulp Fiction poster) this is perfectly fine. But when you don't know and just want to explore what they have, such a text-based browsing system is... well... not optimal ;) What you rather want, is a visual catalogue of their products, which is somehow organized by image similarity. What started out as a research prototype, can now be used by anyone to browse the products of allposters.com visually! You start out with a coarse overview and you can seamlessly zoom into the images. Select one to view it and the one most similar to your selection. For your convenience (and for a small income to cover server cost on our side), you can buy any image you find via allposters.com! Any feedback is most welcome.
