Seen the game - Closure?

Any ideas on how they have made portions of the scenery disappear or appear with light and act as objects that can be interacted with. The mechanics are amazing, the game play/puzzle element is wonderful.

Thought this would be a nice topic to discuss gameplay and how it could have been done.

Any link (especially video) would be awesome.
But from your description, it seems something similar to Penumbear

Penumbear technique is very different. They use black object with predefined shape, scale, rotate and translate it according to light source and shadow caster positions and mask some portion of the screen. The Closure probably use pixel shaders to multiply the lightmap value with under laying pixels
