Those beautiful hands

When we lose interest in everything else, we turn to art. And there are some, who were turned by art to everything else.
The very nature of creativity has bugged cognitive scientists. It is well known that Artificial Intelligence is a field of ongoing research, but what about injecting creativity to machines?
There has been a lot of debate on this matter, and papers published. Nonetheless, they are philosophical deductions only, resulting from present day assumptions. Hardcore scientific results\ideas have not come up.
Even I cannot put creativity to words. The idea that a painter has about a painting he just started evolves and the final look may be substantially different from what he initially visualizes it to be.
Creativity does not have planning. Generally it does not have limits too. And "beauty lies in the eyes of the beholder" perfectly applies here.
There is one scientifically established fact though. Left brain is responsible for logical, rational thinking, while right brain is responsible for creative and intuitive thinking.
