Perfect balance

What is perfect balance?

Obviously this can be defined in science and physics, for some reason I was wondering if you have an object say a pyramid which is cemented together with bonds that will not corrode and bricks that will not diminish. Say you had that pyramid and stood it on the tip of the four sides and spun it. With some things in life you need to begin with a good sturdy base, but with others you just pick something up, maybe from the highest level or a higher level and you build on that and learn of what you should know from the base structure of the system. I am just thinking abstractly, What if such a skill was built from the top down? or if the pyramid was inverted bottom up from top to base?

Thinking futuristic/Scifi-ish would you think that it will be possible to "materialize" things into a structure from a remote point, making buildings in a matter of seconds, or other structures in minutes? Obviously these materials would have to be present at the site, but having them all ready, could it be possible to manipulate them to conform to a design from a control panel?
