I like the idea of this. This teaches an at-a-glance perspective which I suspect is useful when you're standing next to the pile of rocks thinking on your next rock. I'll probably futz with this going into this summer.
In general I really like the idea of physical skill simulators like this. There are people who want to learn, but can't find a teacher irl for one reason or another. If we want to preserve these skills we need to start connecting the curious to effective training methods
