This is a simple project that draws items from a list and displays them in a random order in a second list. It should be fairly easy to understand what button does what, but click the '?' if you're unsure. I built this project for use with model railway shunting puzzles, where it can be used to produce a random order of wagons from a set. For more information on shunting puzzles, I recommend visiting http://www.wymann.info/ShuntingPuzzles/. And feel free to check out some of my other, more interesting projects!
