how does light interact with space ?

During the Visiting School we will be investigating how light interacts with space and geometry.

The above video uses light to color in space. This is done by looking at how light(Rays/Curves) emitting from a light source(the pink dots) bounces and reflects around a space - when the light reflects/hits something it makes panels solid to say light hit it - imagine using this process the other way around? that you use the reflections to control where light will peak through a structure and interact with its surrounding space?

The video was made by our tutor Jens Pedersen using Rhino and Grasshopper.
