I have made a shape, that consists of 12 cubes.
I have put 1 cube in the middle and connected all the sides with other cubes and then I have deleted the middle cube. In 2D, it looks like 8 squares with a missing cube in the middle. In 3D, it looks like a hollow, unfinished cube with missing corner cubes. I have rotated it into an angle view, I saught 3 cubes in the front and the rest was a background and I removed those front 3 cubes, to see what the center looks like. The backside of the 3 cubes in the background creates a hexagon with 6 triangles, also I saught a cube which doesn't exist, an optical illusion in the middle, which looks flipped compared to other cubes. I could post a picture, but I have no idea how. It's an idea to present a mirror dimension. What do you think?
