I simply tied the end of a paintbrush onto a twig.

If they don't have the will or the tools to go out there with guns, they'll go out with a paintbrush.

To me, thought controlled computing is as simple and powerful as a paintbrush one more tool to unlock and enliven the hidden worlds within us.

Suddenly, we humans, a recently arrived species, no longer subject to the checks and balances inherent in nature, have grown in population, technology and intelligence to a position of terrible power. We, now, wield the paintbrush.
