Nice little idea! Another nice addon would be trees or bushes. The guy can get wood or berries out of them, or, if you don't fell like it, just walk around the while avoiding them

What a nice idea! I never saw or use the johnny castaway screensaver, but an acquaintance of mine did and it left a very deep impression on him, he always remembered it.

This also looks like the kind of project that is perfect to test the beehive addon, or any kind of npc AI, maybe I will do something similar if I want to play with that sort of things in the future. Inspiring!
