The imagery of Spin-Off remixes the Dream Vortex and the realities of the CAVE (Computerized Automatic Viewing Environment), a room with interactive projections for which Dream Vortex was originally intended. A CAVE's virtual reality may confuse users about where “reality” stops and starts. The passage in Spin-Off with grids sliding from 2-D image to 3-D material refers to a green grid that popped up in the CAVE if a user was in danger of crashing into the projection screens. In the CAVE, image size was elastic. To get a more intimate view, instead of moving towards an image (as with a painting) viewers enlarged it; as suggested in Spin-Off with a red drawing repeated at different scales. Fluid scaling destabilizes the relationship with the physical world, foretelling the uneasy mix of pleasure and nightmare in the dream images and objects encircling the space.
