Truly one of the most elegant implementations of all the basics that one could ask for.<p>In case you haven't dug into this dear reader, the Lunar Lander example is fascinating! Takes a bit of patience to set up, but is truly fun.<p>I'm left wondering at what other kind of hijinks a real, life-size ANALOG THING could be pressed into executing .. in a general sense I've always personally had a fascinating with analog computers in other forms - pinball machines, electronic music synthesizers, the flowerbed - but have spent nearly all my life attached to a digital one, in some way or another.<p>As I see it, a gravity/water-based analog thing is doable, and .. one fine Sunday afternoon, might be the perfect thing to design/prototype with whatever ML model will be waking up for some pushing around.<p>If there were, say, an electromagnetic means of tracking the state of a pinball as it traverses the playfield, and of course if the drop targets and bumpers and switches and things were all appropriately wired up, I wonder what it would take to program an analog computer thing to play a mean pinball...
