OOOO i got an ideas!

Seeing as i will be looking at how to render forms at varying distances I'm obviously going to be paying a lot of attention to scale. If i draw something at a small scale and then blow it up much larger will it still communicate correctly and be readable as the same object?, and vice-versa if i draw something larger and shrink it down will it become to crowded and become just a miss mash of colours? It would be an exploration of how our eyes lie to us when we view our surroundings, at what point does what we recognise as an object from memory take over what we are actually viewing?
