Will post more about Christmas in a day or two but I wanted to share the Lego project Tau and I worked on yesterday.
This is his first set from the Lego Technic 2-in-1 range, models that focus less on bricks and more on building with levers and gears. This particular model builds into a monster truck with suspension and working front-wheel axle to turn the wheels. You can also rebuild it into a truck/trailer. The slideshow pretty much says it all — enjoy!
