Don't get me wrong: I think Maekawa's original is absolutely amazing, but it's an interesting assignment to 'upgrade' an abstract or simple model to something more realistic and detailed...
In the picture below you see Maekawa's original and my own adaptation...
My challenge to you is: can you do something similar to one of your favorite simple designs???
