At the forefront of the current reality today is getting a prototype. In its origin there was a concept that we really can not produces anything new. But today, we have the ability to create through the use of 3D printing.
3D printing allows us to dream it then bring it to fruition. The ideas that we have today can be the result of what we hold to be true and can physically produce. If you can see it, you now can create it with 3D printing.
Not everyone will go out and buy a 3D printer. That said, most people will not have the engineering capacity to create something original from scratch.
