It was a really modern-looking, fresh, grayscale style that had an almost "pressed" and kind of Apple-like asthetic. If I remember correctly only bits and pieces were posted but it was very-professional looking.
I think they had a vBulletin version already and they were thinking of creating a more-refined XenForo version. It wasn't one of the major style devs, I hadn't really heard of the person before.
Anyways if anyone could point me in the right direction it would be greatly appreciated. I feel like I'm going crazy.
