Transcrobial explores the emerging relationship of humans, microbes, and machines. Machine learning and generative adversarial networks (GANs) are incorporated to mimic and expand upon bacteria evolution and pattern formation beyond what is realizable in the physical world. Transcrobial focuses on 'bacteria swarming' patterns, which are emergent behaviors that these microscopic organisms coordinate to form macroscale, fractal-like structures in an amazing feat of community intelligence. GAN-based artworks have been created using existing Gihub tools (R. Barrat, S. Chintala). Ultimately, the work reveals how the transient biological existence of life through evolution can be artificially generated, and communicates fundamental perspectives of the human condition and interaction with living and non-living entities that speak to our collective futures.
