PC World has published a list of the oddest / most awkward / most useless videogame accessories of all time.
Included in the list:
"Granted, it was supposed to read muscle movement on the head, not brain-wave patterns, but it was a start."
The Nintendo Power Glove:
"symbol for all that is unholy, wrong, and dorky with game controllers"
The Laser Scope:
"it's pretty hard to top Konami's LaserScope for sheer date-nullifying nerdity."
"A controller that gives you a mild shock as you get your butt kicked."
