I know exactly what you mean. I think splatter painting is the way to go; i thought about doing it once so i shot at some extra drywall I found in the basement. The first problem was that the paint ran down the wall instead of sticking to it, the second problem was that it dried into a powder.
I've done some splatter painting as well and if you do it right, you can get a nice effect. the key is to not get a lot of paint on the brush of it globs on the wall.
......now everybody is going to think I'm a fruitcake
