When we think of art, fungi are not usually the first medium that comes to mind. However, [Kexin Wang]'s innovative project, Funguy, challenges this notion by harnessing the power of laser control to create intricate fungal art. This unique approach to artistic expression is not only visually captivating but also opens up a world of possibilities for both artistic and educational endeavors.
The Science Behind the Art
At the heart of Funguy lies a sophisticated computer model that predicts fungal growth patterns. This model, developed through a research project, consists of two key components: a temporal convolutional neural network and a cellular automaton. The neural network learns growth patterns from a series of images, while the cellular automaton simulates these patterns under varying conditions. What makes this model particularly fascinating is its adaptability; each cell within the automaton runs a small neural network that learns the rules, guided by the convolutional network.
By training these networks on the growth stages of three distinct fungi species, the model can accurately predict their unique growth patterns. This level of precision allows for controlled growth, a concept that was further explored through experiments with different laser wavelengths and powers. Interestingly, shorter wavelengths proved more effective, with a 405 nm laser emerging as the optimal choice.
Controlling Growth with Lasers
The growth model is seamlessly integrated with the laser setup, predicting areas where nutrient depletion may occur. As fungi cease to spread in these regions, the laser can be strategically directed to trace only the necessary sections. The laser system itself resembles a laser engraver, utilizing an XY-kinematic system built from a DVD drive frame. This innovative setup showcases the potential for precise and controlled growth, with the Mucor genus of fungi serving as the primary medium, although other photophobic microorganisms, such as slime molds, can also be used.
Beyond Art: Functional Applications
While Funguy's initial focus is on artistic and educational uses, the project hints at a broader potential. Considering the diverse electronic components that have been created using fungi, it's not far-fetched to imagine more functional applications for this unique medium. From biodegradable electronics to computer memory, the possibilities are endless. This project serves as a reminder that art and science can intertwine in unexpected ways, leading to innovative solutions and a deeper understanding of the natural world.
A New Perspective on Growth
Funguy challenges our traditional notions of growth and control. By manipulating the environment and growth patterns of fungi, we can create intricate designs and explore the boundaries of what is possible. This project invites us to take a step back and appreciate the beauty in the intricate processes of nature, offering a unique perspective on the world around us. It's a fascinating example of how science and art can converge, pushing the boundaries of our understanding and imagination.
