It's common for us to attach different emotions to each moment in our lives, but when we capture and interact with them, we are often constrained to flat, 2D encapsulations of video, audio, or photographic recordings. In this digital age we often look at memories through a screen with hundreds of digital files, further removing the event's emotion. What if we could experience this emotional energy again, and dynamically interact with it in infinitely complex ways? We present a concept and prototype that explores a novel physical-visual language of dynamic, emotionally expressive waveforms, designed to transform how we perceive different forms of energy in our daily lives. With the power of computation hidden within the physical materials of the interface, we create an interactive form that takes one form of energy and transmutes it into a waveform as its output, or Wave Alchemy.
