It's a pool table, I built it after I saw a green plate that I had in my collection. I've loved playing pool ever since I was in high school, and there are plenty of other pool enthusiasts out there. I found the use of lightsaber hilts to be a viable set of pool cues. Since LEGO doesn't make pool balls, I came up with the idea of seven solid and seven see-through studs, plus one black stud and one white stud for the balls. I also made a piece of chalk out of a couple of studs. I hope to bring many more ideas to your attention in the future.
