The initial design of these hexagonal spiked pyramids intrigued me. The next step that I saw in the development of the tile was to give the variation of each module a meaning and move away from a randomness.
The modules movement is based upon a line, or path, that it is “attracted” to. Its distance from the closest point on the attractor determines the height it moves, as well as the amount of pull, or gravity, that the attractor pulls with. The closer the module to the line, the shallower the height, and less movement of the peak to the line.
The path given to this example is a simple arcing line through the tile.
