The work of Florian van Zandwijk explores the inherently playful nature present in the early stages of technological development that ultimately evolve into highly complex systems. In this case, 𝘞𝘢𝘭𝘬𝘪𝘯𝘨 𝘵𝘩𝘦 𝘙𝘶𝘯𝘸𝘢𝘺 examines the foundations of artificial intelligence, computer vision, and dataset creation, highlighting how their initial forms often emerge through experimentation and exploration before becoming integral to sophisticated technological frameworks. Just as handwriting and fingerprints are unique to individuals, so too is the way each person moves. Our posture, pace, and motor skills form an unmistakable biometric signature. Twenty years after the creation of this dataset, the original actors—like all of us—could be uniquely identified in a crowd based on their gait alone.
