The distortion doesn’t seem quite correct.&lt;p&gt;I wonder if this is actually a clever cheat. Perhaps it’s actually not transparent, but a mirror surface and the cube map for reflections is actually just the skybox inverted. So instead of actually looking through the glass sculpture, it’s reflecting the inverted skybox.</text><parent_chain><item><author>jessep</author><text>I found this one by the same person even more amazing.
