The present invention relates to a cathode ray tube having an improved electrical connector. A path of the continuous strip from a first end to a second end is circuitous and includes a plurality of repeating cycles, each of which includes a plurality of first straight segments, a plurality of second straight segments and a plurality of radiused segments. An electronic processor disassembles the image and presents the disassembled image to a user by a graphical user interface as an authorization challenge. The cup-shaped intermediate element has a spherical inner face. Each arm has a proximal camming surface and is capable of rotation with respect to the body.
