I've always liked the idea of animated maps (didn't you make a Mega Man III one of Shadow Man's stage a while ago, Revned?), but I didn't think it would be easy for a large map like A Link To The Past's. Certainly would be bulky in GIF form. But this page you have shared is really neat. Considering it's one of my favourite games, of course I would like it, but still, wow! (And it really reinforces my point about later Zelda console games' overworlds being too quiet in comparison...)
The dungeons would be neat to see. Would bosses be actively moving around when Link isn't there yet though? For example, Kholdstare starts out frozen, doesn't he/it/them? I guess that's a creative choice you will be making...
