People keep making cool stuff with OpenSeadragon! I've been collecting links to add to the "In The Wild" page for years, but I keep not getting around to updating it.

Here's the collection: github.com/openseadrago... Anyone want to bring some of them over to update the page? 😄

The New York Times just published a piece using OpenSeadragon:

www.nytimes.com/interactive/...

They challenge you to slow down and spend 10 minutes with the painting, exploring it on your own. Afterwards they tell you more, giving you context to add to your own observations.
Can You Spend 10 Minutes With This Painting?
We’d like you to look at one piece of art for 10 minutes, uninterrupted.
