A "artistic operating system" made up of printers and a barcode scanner. http://screenl.es/
Looks like a barcode scan amounts to clicking into an article - probably feels satisfying to do
Receipt printers seem to be in use as well
I don't see any videos of the full system in action but it's kind of fun/evocative to guess at.
Adding barcodes + scanner to my list of physical things that can provide digital-like interactions. Along with QR codes, apriltags, hand/finger-tracking, touch frames.
