A lightpen for the Amiga from the makers of the infamous trojan lightgun. The lightpen connects to the joystick port of the Amiga and drivers were available for both Workbench 1.3 and Workbench 2.x+. The lightpen colour settings in the program Quickdraw are very sensitive and altering these means that you may have to have the lightpen touching the monitor at all times for it work, rather than the acceptable range of 1 - 1.5cm.
