Claim 16:
17. A tactile graphic display comprising:
a frame; and
a plurality of pin assemblies forming an array, 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; and
a latch member configured to selectively engage a slot defined between the pin and a ledge of the pulser member when the pulser member is in contact with the second end of the pin for locking and unlocking a position of the pin relative to the frame; and
a magnet responsive to an electrical current and disposed proximate a second end of the pulser member, the magnet and the pulser member capable of transitioning between different positions relative to the frame;

wherein a position of the magnet and the pulser member determines whether the latch member is selectively engaged or disengaged with the slot.
