Glowing Bacteria Art – Stocker and Nestelbacher’s GFPixel.

Austrian artist Gerfried Stocker and molecular biologist Reinhard Nestelbacher collaborated to create this unique "painting" made from genetically modified fluorescent bacteria. These bugs are arranged in thousands of petri-dishes – with the pattern determined by the gene expression of the fluorescent protein (called GFP or green fluorescent protein, hence the title of the artwork).
