Prototyping on the Mu computer
A 3-minute video showing what it's currently like to prototype programs on the Mu computer.
There are lots of limitations. It's slow, and it can only handle short runs.
While these limitations will be relaxed over time, the goal is partly to nudge people to throw the prototype away once they know what they want, and rewrite it one level down. Therefore: encourage people to write lots of tests.
