I'm making a character sheet for my next Planescape(-y) campaign.
As I want alignment to play a part, and give my somewhat clueless players a reminder of the Great Wheel, I thought I'd incorporate this tracker on the first page.
The scales show how much into the alignment the character is, and you mark where you are on the chart.
What the characters do will affect their place on the chart.
(There's a flaw that the worst extremes, 5-5's, place you outside the wheel 
That's an argument for using Gygax' square from 1st ed PHB - but I like the wheel.)
Essentially a 0 or 1 is neutral ground. 3 is 'normal' for the alignment, while a 5 is more extreme than most mortals ever are.
I'm thinking about having some sort of reaction adjustment based on how far away you are from each other, but don't know if I'll codify it.
What do you think?
Nice work!
