<p>An interactive pin array device comprising a plurality of elongated pins held in a frame and forming a set. The frame is adapted to hold the plurality of pins in a parallel position to one another in a series of columns and rows, such that the distal ends of the plurality of pins together form a flat virtual plane. Each pin of the plurality of pins includes an elongated housing member defining a linear axis therethrough, and a pin member adapted to slide linearly in either direction along the axis. Each of the housing member includes an upper electromagnet, and a lower electromagnet separated from the upper electromagnet.</p> |
