So there is this impulse of DIY randomizing. DIY is good, period. And there is this disdain for computer based randomizers (actually I'm fine with them but let's accept that a randomizer physically present in your hands has an edge). Still I like something about computer science: playing with binary numbers. I know I'm already knee deep in nerdspace. Sorry it won't improve, please hit the "back" button now if you're appalled.
A number can be represented in binary, that means only two digits are available : 0 and 1 (yay me!)
So if you see this binary number 10101 it starts to be a little difficult without practice, or without going into details :
10101(binary) = 1 * 2pow4 + 0 * 2pow3 + 1 * 2pow2 + 0 * 2pow1 + 1 * 2pow0 = 16 + 0 + 4 + 0 + 1 = 21
where 2powN means 2 power N (2pow0 = 1, 2pow1 = 2, 2pow2 = 4 ....)
Right now I've got the math/computer geeks thinking "well duh" and the others going "booooriiiiing". Let me toss pennies in here !
So each digit of a binary number could be randomized by the toss of a penny, right? right. So for a randomizer equivalent to a d8 one needs 3 pennies. 4 pennies for a d16 etc... So a BinaPenny randomizer
(there I named it) would be better used for dX type of randomizers, where X= 2powY. that's a first limitation.
The next problem is when tossing a lot of pennies how do I know which penny correspond to the higher digit, and the next one and the next one... Well given a flat surface where the pennies landed and given the position of the guy who tossed, we could rule that "the higher penny is on the extreme left of the tosser view, and next bits are read by reading next pennies from left to right". It should work, except for the weird cases of pennies aligned from the tosser POV.
Well ok so now I've got a binary number randomly generated by throwing pennies on a table. It still didn't make binary representation easy on most gamers. We still prefer decimal numbers in general (OK except for time and weird non-metric units). Sure I can solve that by having a sheet of paper with let's say the first hundred binary numbers and their decimal translation. Weak sauce. That's where story-games design geniuses kick in.
