Play and the right brain: Have I come to another crossroads?

Once again I have have come across something that could change the outcome of my thesis. I'm still playing around with the idea (no pun intended) and once my thoughts on it have solidified it may be integrated into the final pieces.

Currently I have three outcomes for my thesis with one basic goal: education. My thesis is to educate people about visual intelligence and its importance. This includes helping people engage their own visual intelligence, through visual thinking, to strengthen it. By strengthening it they will be able to integrate it into their current ways of thinking, acting, working, etc. Often using more than one way of thinking can enhance the solution and outcomes even if it means exhausting other possibilities so that you are sure of your original solution. 

Out of pure interest I was watching a lecture filmed a the Serious Play Conference held in Pasedena, California in May 2008. The lecture was given by Stuart Brown on Why Play is Vital -- At Any Age. He discusses the biological implications of play and why it is important for us in areas such as problem solving. There was however a very specific point he made that started me thinking about its importance to my project. 

He was talking about a mother and baby and how they interact and play with each other. If they were hooked up to an electroencephalogram (EEG), which records the firing of neurons in the brain, that the right side of their brain would "become attuned." The right side of a typical brain houses your visual centers and as well as your spatial centers and is often associated with imagination. 

Taking this into account, would it be useful to use play as a method of helping people tap into their visual centers and their right brains?
