Grab handles are the little boxes that appear on the corners and in the middle of vector-based objecrts in either 2D or 3D manipulation in many packages. They can be grabbed by a pointing device, and dragged to resize the shape. Many graphical virtual environments utilise them, for the ease of resizing they offer.

Walking through the orchard on a warm summer day, the smells of nature in your nostrils, the soft padding of grass underfoot, you reach up a hand, and grab a juicy red apple from a tree, plucking it delicately. You bring it to your nose and smell the fragrance, then you bite into it. It is like chewing rubber. Completely tasteless. No juice, no sweet flesh, you cannot even detect it in your mouth.
An interesting discovery has come out of a study by researchers at the Hebrew University of Jerusalem and at New York University and Princeton University. Namely, the discovery that the face is not the primary communicator of emotion. The rest of the body handles that. This is of course critical for our virtual environments and their avatars.
There are several potential ways this display is working. One of the simplest and most plausible is a colour e-paper display behind a completely transparent display medium. The e-paper handles the picture, 'refreshing' the colour display to a matt black when the layer in front, the graphical display is activated. As soon as that deactivates, the 'oil' is re-drawn. Simple, elegant, and still far beyond us.

This episode speaks of the healing power of virtual worlds in all but name.
