I never got that far, but I once built a little page that just visualized embedding vectors generated from a few hundred cat, dog and plane photos as heatmaps. I used this for demonstrating to database & storage folks what embedding vectors physically are, at low level. The point of the heatmap (of different vectors) was to show that there are visually observable "vertical bands" standing out when plotting out many embeddings of the same types of objects (like different cats with different backgrounds) in a single heatmap.

I then also took a single cat photo, rotated it by one more degree 360 times and created a heatmap of these vectors to illustrate the point of what the embedding models really detect (you have to uncheck the "Normalized" checkbox in the "same cat rotated by 360 degrees" page to see the vertical bands show up).

The web-app is here:
