Bubbles take up minimal surface, and that configuration is the minimum surface area that a bubble can take given the structure that it's inside. It's actually a very complex mathematical problem to figure out the minimum surface area, but if you can make a real life model of the shape you're trying to solve for, then the bubble can be used to give you a physical solution. If you're good enough, you can probably use this to help you derive the mathematical formula.
Another interesting device is using electricity to determine groundwater flow, because the equations for electricity and water flow are the same. Before powerful computers, you could hook together a 3D wire mesh with capacitors and other electrical components that acted as wells, high and low water pressure points, and when you ran an electrical current you got lines that indicated the speed of water transport through the ground. It was an absolutely brilliant invention.

It's the shadow of a fourth dimension where that shape is made completely of segments locking together at right angles!

Correct me if I'm wrong, but wasn't a tesseract the fifth dimensional cube?
