The National Toy Hall of Fame is a U.S. hall of fame that recognizes the contributions of toys and games that have sustained their popularity for many years. Criteria for induction include: icon status ; longevity ; discovery ; and innovation. Established in 1998 under the direction of Ed Sobey, it was originally housed at A. C. Gilbert's Discovery Village in Salem, Oregon, United States, but was moved to the Strong National Museum of Play in Rochester, New York, in 2002 after it outgrew its original home.
Etch A Sketch
Basic mechanism of operating a 2-dimensional plotter. The numbered components correspond to those that move the stylus horizontally, and the lettered components with those that move it vertically. The device has ten pulleys, six cables, two rails, and a stylus. Pulley 1 (single-groove) connects to pulley 2 (triple-groove) via a short infinite reciprocating cable. Pulley 2 connects to 3 (double-groove) via a longer reciprocating cable attached along its upper course to one end of the vertical rail (6), and then a third cable runs from 2 to 3, 4, and 5 (4 and 5 are single-groove) via another much longer loop of cable between 4 and 5 to the other end of the vertical rail. Likewise, A connects to B, B connects to C and attaches to the horizontal rail (F), and finally B connects to C, D, and E, attaching to F at its other end between D and E. Turning pulley 1 counterclockwise makes 2 rotate the same way, and this makes all pulleys connected to 2 (3, 4, and 5) do the same. The rail these cables connect to (6, connection points marked in red) moves to the left with the cables attached at each end, making the stylus move in the same direction along the other rail (F). Clockwise movement of pulley 1 has the opposite effect. Pulleys A–E operate the same as 1–5, and act on the horizontal rail (F) to slide the stylus up and down along the vertical one (6).
