I would like to help! I use Celerity in the default skin; I did turn the beta option for the site skin on, but I can turn it on and off as needed for testing. My reaction was immediate but very mild.

Photosensitivity is so weird! There is absolutely nothing about the new site skin that had ever been on my Makes Brain Weird list, and yet I opened a post in the new style in a tab and immediately brain = weird? Who knows.
