Carman and Sudoku have been learning and experimenting with SketchUp, Google’s free 3-D modeling software. Carman has caught onto the concepts and maneuvers pretty quickly. Here’s a model he made of a lamp in our home. If you could spin the model around, as you can with the 3-D software, you could see underneath the lamp shade where there are metal spokes. He did a great job with this project.
