If you have a webcam, rotate the LEGO cat by moving your body. Otherwise, you can use the arrow keys. Here's first version of this project without camera sensing: http://scratch.mit.edu/projects/1017438/
LEGO built the cat and gave it to our group at MIT. Ericr is part of our group and helped design the 3D virtual model, then LEGO built it. Others on the Scratch Team offered suggestions, such as how to make it balance (by holding the sign instead of having its tail on the ground).
