Such a strong lens/viewpoint for this one. I feel as I learned new things about our world even though you present a fictional to prospective players. The rules and presentation are so simple but really powerful. You've given us something VERY deep. It took me a minute to realize you meant the ACTUAL intimate act of adding stripes (to that end you may want to suggest players can also use gel pens - I used to draw on classmates with them because they wash off easily).
