Folk Computer, an open‑source physical computing system created by researchers Omar Rizwan and Andrés Cuervo, was demonstrated in a Brooklyn warehouse in June. The system uses printed sheets of paper as programs; cameras track the sheets, projectors display interactive content on surfaces, and participants manipulate paper and markers to write code and create animations in real time. The demonstration showed the program running directly from the paper without a monitor, allowing multiple users to collaborate in the same space.

The system builds on earlier work from Xerox PARC, the CDG lab at SAP, and the nonprofit Dynamicland. It differs from traditional desktop computing by treating the room itself as the computer, eliminating pixels and using spatial coordinates measured in meters. Developers can set up their own instances using GitHub repositories, and community contributions have produced tools such as a card‑based music sequencer.

The author, an investor who also serves on the ACM’s Professional Development Committee, noted that the computing field has recently converged on agent‑based research, limiting exploration of alternative paradigms. He said that early‑stage paradigm work relies on patronage rather than market demand, and that Folk Computer offers a way for independent researchers to pursue unconventional ideas without immediate commercial pressure. He invited interested individuals to contact him for introductions, funding, or collaborative opportunities.

The demonstration highlights a resurgence of experimental computing that traces its lineage from the 1970s to present‑day open‑source initiatives, suggesting a potential shift in how software is conceived and built.
