My son and I were playing with Legos a while back. I started playing with this arm piece that looked rather menacing. As the thing grew, I knew it needed an environment to go in. Once you go down that road, it’s all over. I then had to come up with other stuff to put in there with it. Then those things were cooler than the robotic arm thing. One thing led to another and eventually I had a full on nuclear looking power plant.
