Interactive Drawing

I'm currently working on my next project for my Fine Art course; an interactive drawing. I usually do a lot of detailed ink drawings, most of crazy scrap worlds...but I've been thinking of creating a drawing that you can actively EXPLORE and 'walk around' in, as opposed to gazing passively at a piece of paper on the wall.

I'm hoping to do this via Unity; I'll draw the parts as usual (with Wilkinson's cheap gel-pens in a sketchbook, haha!) scan them in, and then create the world using my drawings.

So far, I've drawn up some walls for a shack:

I'll get to drawing up a roof and maybe a floor tonight, and see how things go! If it's successful, this will combine two of my favourite things; drawing, and video-games. (All that's missing is metal, haha! Maybe I should learn to put music in Unity!)
