Cars, mostly the same as in the course.
And a few not in the course.
Including larger trucks.
Tripods, from the course.
More modular walker/roller/treaded things.
And an example of how they might fit together.
Tanks, mostly the same as the course.
Trains, including one with a bunch of walkers on it.
Planes & Helicopters, straying far away from the modular approach, but enjoyed making them anyway.
And ships & hovercraft far away from any resemblance to modular.
Really enjoyed this section, and am still reluctant to move on.
