This is world map colony on the culture medium.
I reuse the petri dish that was posted on my previous post(Blender CGI: Cultured Escherichia coli in Biotech Lab).
The world map is also reused from the curve I created from svg(3D worldmap by D3.js and Blender via SVG).
The colony is the aggregation of spheres that grow as particle hair on the world map curve.
From back.
I found that the round edge of petri dish makes it look like the earth. It reminds me of The Trueman Show.
Some parts of the colony emit red light. It’s a mock-up test of data visualization.
