The was some program source that I thought Mars or Robert Purves wrote that did a scatter dissolve. The algorithm in particular was actually pseudo-random where all the points on the screen were covered BUT they were covered in a way that looked random but really wasnt. I'm looking for a way to "randomly" choose items from a list. Once the item has been chosen, its removed from the list and hopefully this "random" method wont choose that item again. Thanks, W.
