A generative video projection of 2000 QR codes in a matrix.
Each QR code undergoes a complete, random transformation 240 times per second, with the changes occurring simultaneously. The speed of transformation is calibrated to be near the limit of modern smartphones' scanning capabilities. The source of the random data for these transformations is analog noise, derived from an overdriven transistor (see my work on TRNGs).
Since the QR codes are generated through a physical source of entropy, they theoretically hold the potential to display any form of information at any given time.
