Being an engineer, I am always interested in the origin of things. We all know that velcro was developed for use in the space program when there was a need for a dry, re-stickable closure that would work at a wide range of temperatures and in a vacuum without deteriorating. Today, velcro is everywhere - so much so, in fact, that we can all immediately identify the sound of a velcro closure opening. I know that there are several outcomes of Disney Imagineering - I can think of the monorail, several means of crowd control, projections on water (Fantasmic) and on nebulized water (Pirates of the Carribean), and the first practical use of halographic projection (Haunted Mansion). Disney has also masterminded so many visual effects that it is mind boggling. There must be things that we use every day that originated at the Disney Studios or Disney Parks. Let's generate a list. Please help me. FJF
