Oberon is one of the great under explored operating systems/user interfaces. Now you can run it in an emulator, including a compile-to-WASM one in your browser: http://schierlm.github.io/OberonEmulator/

This is awesome! Modula-2, Oberon, and Dr. Wirth's work has been on my radar for a long time. His work is definitely underrated. My favorite hobby language, Nim was heavily influenced by Modula-2. The creator of Nim, Andreas Rumpf, was a student of Dr. Wirth.
