This is from the Wesleyan (CT) student center. They had a men's and women's room plus this single stall multi-gender bathroom
Please don't mistake me for a cultural conservative here. I am not complaining about this or posting it as a sign of the apocalypse. I actually think the one stall multi-gender bathroom (which a lot of public buildings already have but they are simply called "family" bathrooms) is a reasonable accommodation for those who struggle with the typical two gender classifications. I did find the third gender symbol sort of funny, and only on a modern college campus would a restroom sign need 14 words of gender explanation in the (probably futile) hope of not offending anyone.
