I love this zoomable interactive display of British & Exotic Mineralogy. To create it, Nicholas Rougeux collected 718 hand-drawn mineral illustrations by James Sowerby sourced from a pair of multi-volume books called British Mineralogy and Exotic Mineralogy, published between 1802 and 1817. Then he arranged them according to hue and brightness in a collage worthy of Knoll.
