some incredible person rewrote warren robinett's Robot Odyssey (apple //) for browsers
if you've never heard of it: you explore an underground city of robots by... hopping inside of a robot, visually reprogramming it by picking up and dropping things, and then using it to do stuff
crazy great #ui design, especially considering this was 1984.
the code would be later torn apart and repurposed for other games in the Learning Company's library, like Rocky's Boots.
