And by modulating the amount of blue in our environment, we can help people to relax, or to be alert, to fall asleep, or to stay awake.

The role of snow cover in modulating the monsoon is just one example of a short term cryosphere climate feedback involving the land surface and the atmosphere.

And by modulating the amount of blue in our environment, we can help people to relax, or to be alert, to fall asleep, or to stay awake.

And if we can actually provide feedback, sensory signals that go back from this robotic, mechanical, computational actuator that is now under the control of the brain, back to the brain, how the brain deals with that, of receiving messages from an artificial piece of machinery.

And we make a mathematical model of those relationships and program them into a tablet computer so that when you take the stylus and go and touch the screen, that voice coil actuator in the white bracket plays vibrations to give you the illusion that you're touching the real surface, just like if you touched, dragged back and forth, on the real canvas.
