In the world of art, preservationists often strive to keep fungi at bay, but Kexin Wang's Funguy project takes a unique approach by harnessing the very essence of fungi as its artistic medium. This innovative project uses a laser diode to meticulously trace intricate designs onto a dish of agar gel, where the photophobic fungus thrives, growing only up to the edge of the laser-traced figure. What makes this concept particularly fascinating is the underlying technology that enables such precise control over fungal growth. The project evolved from a research endeavor, where Wang and his team developed a computer model for fungal growth, employing a temporal convolutional neural network and a cellular automaton to simulate and predict growth patterns. This model is a marvel of machine learning, learning from a series of images to forecast the behavior of fungi under various conditions. The neural network's ability to adapt and learn from its environment is a testament to the power of artificial intelligence in understanding and manipulating natural processes. What many people don't realize is that this technology has the potential to revolutionize not only art but also functional applications. The laser setup, reminiscent of a laser engraver, works in tandem with the growth model to predict nutrient depletion areas, allowing the laser to trace only where the fungus can grow. This precision is crucial for creating intricate and detailed designs. The Funguy kit, with its laser system seemingly crafted from a DVD drive frame, utilizes fungi from the Mucor genus, although it can accommodate other photophobic microorganisms like slime molds. This project is not merely a curiosity; it opens up exciting possibilities for artistic expression and educational exploration. Personally, I find it intriguing how this technology can be applied to create biodegradable electronics, as suggested by the Hackaday article. The potential for myceliotronics, where fungi serve as computer memory, is a fascinating development that could shape the future of sustainable technology. In my opinion, this project is a brilliant example of how art and science can intertwine, offering a fresh perspective on the role of fungi in our lives. It raises a deeper question: What other hidden implications and applications might emerge from this innovative use of fungal growth?
