What is this?

I've used LFE and Elixir (and other tools) to follow the Nand2Tetris course, which guides "self-learners through the construction of a modern, full-scale computer system - hardware and software - from the ground up. In the process, the students practice many major computer science (CS) abstractions studied in typical CS courses and make them concrete through 12 guided implementation projects."
