Below is Intangible afterimage star (2008), in which six spotlights project blue, yellow, magenta, green, and turquoise geometric shapes that constantly intersect and layer. As the intense projections fade in and out, complimentary afterimages briefly linger on the viewer's retina and appear to multiply the color compositions, combing with the actual image to create a magical effect. It is notable that film is only partially produced by the spotlights' projection, and the viewer's participation is only internal.
Is this a good/useful/informative piece of content to include in the project? Have your say!
