Thank you Varian for that insightful look into that picture, which is not exactly what I wanted to do, but just a version of the ducky... :) The thing on the corner that your sharp eye has detected was originally meant to be somethign to distract from the sameness of the walls, but could also be the embryonic beginning of something full of color and life beginning to develop in this nether world... So, we'll see if I finish the original vision... I still haven't finished the underwater tutorial picture... :)
