A cool new tower in Moscow made me think... the shapes of the structures that have lasted the longest are all pyramids. Whether stepped or sloped they shape mimics nature, and the closer the shape matches the hills and mountains of the setting, the longer they will last (just a prediction). So this pyramid is nothing like the pyramids of antiquity, but it does take a cue from their lessons. Either way, it is cool looking but who knows how well it will ultimately work, or how long it will last. All of that depends on the care that is taken in it's design, construction, and maintenance. I can certainly imagine the solar opportunities on those long, even, sloping facades.

Also worthy of note is the structural advantage and stability of triangles and tripods. Good work Sir Foster, yet again.
