I guess its a difficult concept to really define, but an entrance etc can be anything from a spiritual thing to just an ordinary door in the real world, which is why I said either metaphorical or actual. I thought it would be interesting to see what people came up within the concept. The idea of the challenge arena is that all sorts of artists use their own preferred media, be it 2d, 3d, fractal art, photography or whatever, rather than just competing in their own separate forums. Can give a really wide spectrum of images.

The greatest part of wisdom is learning to develop  the ineffable genius of extracting the "neither here nor there" out of any situation...."
