1. A tactile graphic display comprising:
a frame; and
a plurality of pin assemblies extending through the frame, each one of the plurality of pin assemblies comprising:
a pin having a first, finger-engageable end extendable and retractable through an opening in a surface of the frame;
a pulser member having a first end configured to contact a second end of the pin, a portion of the pulser member defining a ledge, the ledge defining a slot between the second end of the pin and the ledge when the pulser member is in contact with the pin; and
a magnet proximate to a second end of the pulser member, the magnet capable of transitioning between different positions relative to a coil;
wherein current applied in a first direction to the coil causes the magnet to move relative to the coil, in turn causing the first, finger-engageable end of the pin to move relative to the opening in the surface of the frame.
