This place. It is not of this world.
Background: I started with the interesting idea of the console being 4 computerish devices and a rotor with actual controls being hidden. Each machine has a hidden control with the monitor and lever in the rotor, which also served to make the rotor solid. From there I built the pillars. Then I made a circle about 5 blocks out from the end of the pillar and made a circle, cut the inner platform to be a circle as well, and filled the gap with slabs. The walls were going to be standard roundel walls but I figured to try something else. Something less normal.
