I love Abraham Neddermann’s Dice Creator’s Blog, full of his experiments with gaming dice. His most recent creation is a lovely hollow twenty-sider he calls Larry Niven’s d20.

Today’s post, can be described as a truly “Concept Die”, like the concept cars you see on many auto shows. It comes as a solution to “The D20 question”, which is, more or less, the unpracticality of a barrel type D20. You know, as you increase the faces number with a constant face width, diameter of the die also increases.

A few days ago, Abraham had tried to make a Hollow metal 6-sider

      And I know weight would be a critical issue here, but I think it would be really fun to put a bearing in the middle and have some sort of weighted pendulum with a pointer on top on an axle running through it to serve as the pointer. But I like added complexity for no good reason. I guess that’s why I read this blog…

        Dang, I need grammar help.

        Bearing with an axle running through it and attached to that axle a weighted pendulum with a pointer on top that shows the number rolled.

        Maybe that’s better?

      Seems obvious but would make a nice ring or set of rings (for different die) and ease of use. Could sell a ton on thinkgeek.
