Would it be possible to use Spout as to create a Plugin that allows the shape of players to change. I know that Mob Disguise lets you disguise as mobs, but I would want a plugin where somepeople could have minor aesthetic differences. Like players with the Permission .ShapeOrc would appear slightly hunched over. Or someone with .ShapeElf would appear to have longer limbs. Just an idea for someone to use! (If you felt like trying!)
