Every so often we like to have a bit of fun with what Tessera can do. This week: postcards!

The Tessera Postcard generator lets you select any 10km × 6km patch of land on Earth and renders it straight from the model's embeddings. You can also render the same location in a range of colour palettes, revealing the depth of information hidden in the embeddings.

Below are a few more postcards from our archive, minus the location labels this time. Have a guess before you reveal the answers.

Fancy making one yourself? Head to the [postcard generator](https://tee.cl.cam.ac.uk/postcard.html), pick a spot that means something to you — home, a favourite holiday spot, wherever — and send someone a postcard of how Tessera sees it.

The Tessera Postcard generator is a feature of the [Tessera Embeddings Explorer](https://tee.cl.cam.ac.uk/), our browser-based tool for interactively exploring, labelling, and building lightweight classifiers on Tessera embeddings, no coding required.
