Planetscale explores caching in a highly graphical, animated and interactive way. I've been working on a hydrological problem involving relocating a river and Planetscale's animated interface helped me understand some fundamentals about short-term detention and release of water flow that I hadn't realised before. I suspect there is a lot of heuristic depth for other disciplines to learn from their approach. Planetscale self deprecatingly describe their approach as just scratching the surface.
