amazing art/craft by Hubert Duprat and the Caddis

I just found these images and fell in love.

The French artist/sculptor Hubert Duprat gives caddis fly larvae gold to build their tubular cases with, they are so beautiful.

Here is the artist discussing his work, he describes the caddis project starting at 2.30. I like the way he describes it as a collaborative project with himself as the architect and the caddis as the builders.
