I reckon
these are pretty 'irregular', but also very pretty
.
However, I agree with Elsmore that making an "average" 12 sided dice (or other numbers) might be a much more practical and relevant idea. The real question being what numbers should be present?
These could be "average values"
eg
12 sided :- 1, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 6
10 sided :- 1, 2, 2, 3, 3, 4, 4, 5, 5, 6
8 sided :- 1, 2, 3, 3, 4, 4, 5, 6
etc.
Or you could go for high values, low values, extreme values etc, which can then be used in various dice combinations to provide the number ranges required (to represent elite, proffesional, raw, rabble etc).
The point here being that with a bit of laser engineering, you could provide something very practical and IP free . . .
