Atlas Obscura is a catalog of "wondrous, curious, and bizarre locations around the world"
Curious Expeditions is similar (and I believe some of the same people are involved) but delves more into objects as well as places
Dark Roasted Blend is just full of all kinds of amazing stuff, I've found many a Myst-like landscape in the Nature section
Anyone have links to other sites that refresh the artistic sensibilities and give you new mind-bending ideas for Ages?
