Right Brain Left Brain

Here's a thought that I would love to hear what others have to say about this: There's a magical sort of experience that seems to come about when both sides of the brain are engaged in a task. What are some of the activities that engage both sides? In general society is run on a very left-side, logical, numerical system with our advanced technology, computerized systems, etc., while the right brain activities can be seen in action in the arts (all kinds).
