I've got a great idea for Risk that I haven't gotten to try out yet

It seems to me that Risk is a perfect wargame for playing on a corkboard or a magnet board. It wouldn't be too hard to make a paper Risk map and affix it to a corkboard, then buy a few cheap sets of colorful pushpins, in several shapes for each color. Then you'd have all the pieces you'd need to play risk, and you could put the corkboard aside or hang it on a wall when the game needed to go on hiatus.
