Brown University's CAVE (CAVE Automatic Virtual Environment) is an 8' x 8' x 8' cube with projection screens on the front, left, and right walls as well as the floor. The CAVE achieves its 3D effect by combining stereo projection, head tracking, and special glasses that isolate left-eye and right-eye images to their respective eye. These visual properties, as well as a surround sound audio system, make the CAVE an idiosyncratic and highly immersive artistic medium in and of itself.

Proprietary software (Cave Writing) has been developed to allow artists to compose pieces for the CAVE. Most of these pieces originate from Brown's Cave Writing class.
