JPL employees demonstrate how this little prototype Rover with its 8 independently motorized wheels rolls over "rocks"...

Rather than stand in line, here I sketched on top of a trashcan (which makes a good impromptu easel) above the crowd entering an exhibit of digital technology...
One of the most fascinating things on view...a wonderful demonstration of the huge, spider-like "Scarecrow" from the Curiosity Rover, as it appears to intelligently move around "Martian" rocks. (Later I found out that the name "Scarecrow" came from its lack of a brain.) I'm sketching elbow to elbow here with fellow visitors in a large sketchbook. I sat on nearby steps to add some color, listening to the variety of languages spoken all around me--something I love about where I live!

It seemed that every child in attendance left with a pair of 3-D glasses--what fun!
