This is fine, except that it limits those who need to tinker in order to find out how those concepts work. When the elements are visually recognizable and physically manipulatable, you can tinker without having to hold the entire chain on concepts in your mind. It reduces the load and increases the likelyhood of 'playing around'.
I hope some day more of Victor's ideas can be realized through the understanding that visualizing processes allows us to use more of our brain to design and develop or products -- not to mention stumble upon and explore unexpected outcomes.
