The Winogradsky column, invented by Sergei Winogradsky, consists in a transparent cylinder for analyzing microbial life by observing how the metabolism of micro-organisms evolve over time in stratified layers. By producing a small closed ecosystem, the column enables observing how bacteria can survive by providing a temporal and spatial visualization of layers such as in ecology, microbiology.

2002 – Bathsheba Grossman's Crystal Engravings
Artist Bathsheba Grossman has been 3D printing mathematical surfaces as early as 1997. In 2002 she started to use subsurface laser engraving to produce 3D physical visualizations of data from astronomy, biology, and physics. Left image: a piece of DNA molecule. Right image: a 3D map of our nearby stars. The artist explains to us: This medium excels at imaging less structural data such as disconnected volumes, non-compact point clouds, and the convoluted strands of proteins. It works by […]
2018 – Phylogenetic Tree with Real Specimens
As part of a zoology class, evolutionary biologist Leo Smith created a phylogenetic tree of fishes where each leaf is an actual fish specimen. Also see our other entries on physical visualizations built by re-arranging physical items. Source: Leo Smith's tweet (29 April 2018).
