I whipped these up today to see if they work better than a quarter wrapped in white paper (for visibility on the camera). I tried a few different shapes, with all of them coming out the same amount from under the rail. The ball did not hit any of them, even throwing it hard at the markers. I think they will work nicely.
I can print another color to represent my score, and the white will be the ghost. Maybe even add text. Maybe even have one side show 10, and one side show zero, so when it goes around the table you know what lap you are on.
