I finally got around to re-doing my Miskatonic University seal. You can still find the original over here, but these new versions won't have any of the pixellation that one was prone to at larger sizes. Why did I make my own when there are so many other versions out there? Because most of the other seals incorporate elements that further the jokey "wink, wink...Medieval Metaphysics" vibe that I can only take in small doses. More importantly, they weren't freely available for use. These are, as long as you follow the Creative Commons license down at the bottom of the page.
Just click on the picture to get the full-sized version.
