It seems lately I have found a greater appreciation for more unique places to find concept away from the concept artists, and while acting very minimally on these finds as I have been busy I personally hope to pick one or two for UE4 level, but I thought I would share the sources of this unusual "concept".

a lot of sci fi high tech images some abstract some unusual give the page time to load its a near infinite source of images.

Lots of abandoned buildings the great thing about this is it can be a real time capsule so whether you are looking for a post apocalyptic look and feel or a victorian era art deco style it can be found somewhere among the abandonedography collection.
Well thats my two, hopefully you have some more unusual places on the web you are willing to share that you find to be suitable as concept art or reference.
