I wish I had moving dots on real greens.
You can, Steve. It's a bit of a butt ache but with a little practice you might be able to do it. Get yourself a bag of white marbles, stand behind your ball on the green and dump them right in front of your ball. As they descend towards the hole you can get an idea of what's going to happen. If the putt is uphill you actually have to throw the marbles or you could go to the hole and drop them there, like you were viewing in reverse.
You might want to carry a squeegee to gather them up after the analysis of the break and a little something extra for the players behind you as they wait for you to clean up and putt. :-D
