Inspired by Minecraft, Introversion developer Chris Delay began investigating voxels. He built a voxel engine, incorporated some procedural generation experiments, and toyed with physics. The results of his brewing are on display in this Windows-only voxel destruction prototype, which demonstrates the interesting interactions made possible by voxels.
