Abstract: An electronic device, worn like a button, supports and enhances social face-to-face interaction. The electronic button stores information associated with a person's professional and/or personal interests and preferences. This information is continuously broadcast and, when received by another button, analyzed to determine if the receiving and transmitting button possess any commonalities. If a commonality is found, colored light(s) illuminate to let the individuals within the immediate vicinity know a common interest exist. In one version different colored lights can represent different interests.

Abstract: A board-type game to be played by two or more players. The game includes lasers where players selectively divert the path of the laser beams. The board apparatus comprises a surface, bounded by a frame, over which laser beams are directed down symbolic rows and columns which constitute a matrix of squares. Each square is a subregion of the surface piece, and is bounded along its four sides by raised edges which are parallel and perpendicular rows and columns of the board. The raised edges, creating recessed squares, assist in orienting the playing pieces. Playing pieces may contain no mirror, one mirror, or two mirrors (oriented back-to-back to produce separate surfaces reflecting in opposite directions). Playing pieces are placed in a predetermined “starting” configuration on the squares of the gridded surface piece. Depending on whether a playing piece contains a mirror or not, said piece may reflect an incident laser beam from a row to a column or from a column to a row.
