Pictures are flat

Pictures are these tricky things that are actually a flat object and yet we can make normal judgments about the position of objects in the picture as though it were a 3 dimensional objects. What is fascinating to me is that a television screen image can be used – in the case of video-scopic surgery – to make correct judgements about where certain objects are in the three dimensional world that the tools are actually operating in.
