Fractal architecture
Everybody knows fractal images (such as the Mandelbrot ones). They are normally two-dimensional, but three-dimensional versions do exist, too.
With the emergence of 3D printers, it has suddenly become relatively easy and cheap to print out such three-dimensional fractal shapes.
I can’t help thinking that if you use the largest 3D printers that are designed for printing houses, it would suddenly become feasible to get computers to design and build fractal houses.
I’m not sure anybody would really want completely fractal rooms inside their house — I would certainly prefer a smooth floor and a window in every room — but I’m sure the technology could be used for making houses that at least on the outside looked much more organic. There would be no reason to build smooth concrete surfaces when the house printer could just as easily create beautiful details everywhere.
I imagine it would be slightly similar to GaudÃ’s Sagrada FamÃlia, which is also full of endless details.
