Details: Here's an interesting inside-look at the design process for new LEGO sets and pieces. Over the years, Erling T. Dideriksen designed many classic elements for the LEGO company. There are many parts, kits, and portions of kits that have been patented over the years for LEGO, but not all of them came to fruition, and of those not all have lasted for years. The patent for the 2x2 turntable was filed in 1977 (the same year that two-part element was released) and remains with us to this day (although LEGO started packaging it as two separate elements instead of one pre-assembled part years ago), but the motorcycle (filed for in 1982, released in a different form in 1983) hasn't been seen in a kit since the early 1990's.
