Abstract: Methods are implemented in a computer system with one or more processors configured to execute one or more computer program modules in which one or more computer program modules configured to communicate with electronic storage media that stores a set of at least six colors and questions having multiple answers, one of which is a predicted answer, individual questions and their predicted answers being based at least in part on unique color pair personality profiles determined from a color pair and its selection ordering, wherein the set of colors is displayed to a first user and a set of color selections is received from the first user which establish three color pairs (the first being a most liked and second most liked color pair, the second being a third and a fourth most liked color pair, the third being the most liked and the least liked color pair), receiving an answering player's selection of a chosen answer to each question and displaying an answering player's score, wherein the questions asked include

Abstract: A dual-camera 3-D rig has a support, a first camera with a first lens mounted to the support in a stationary position, a structural member with a curve affixed to the support adjustable over a range of positions to cause the curve to rotate relative to the axis of the structural member, and a second camera with a second lens slidably mounted to the structural member so it is free to move along the curve to vary interaxial spacing between the two cameras while the convergence distance between the two cameras is varied by adjustment of the curved structural member over a range of positions. Pinhole lenses are used and a mirror is positioned along an axis of the first lens in a position such that a reflected image of a first camera entrance pupil is at the height and longitudinal position of the second camera entrance pupil.

Abstract: An autostereoscopic 3-D image is provided in a viewing zone without the need for 3-D glasses by use of one or more projectors that project two or more images having projected exit pupils separated horizontally by no more than an average human interocular spacing onto a 3-D forming screen (which is a lenticular or a raster barrier screen) with a substantially smooth and nominally white back projection surface and a front side with multiple individual vertical elements that project left and right images so that the 3-D forming screen retro-reflects projected light on the screen received from a light source back to the light source.

Abstract: A subway tunnel light box for displaying a back-lighted image to a viewer inside of a subway car traveling in the subway tunnel in which a transparent video display for displaying a number of images, such as an LCD, is mounted in the light box and a narrow light source, preferably having a width of one pixel, is positioned in the box behind each of the images at a distance less than a typical viewing distance so that each image is illuminated by an associated narrow light source with an associated narrow light source horizontal illumination angle substantially the same as a preselected perceived horizontal viewing angle calculated for the typical viewing distance based upon a physical height of the transparent video display and a desired aspect ratio of a perceived image.
