I thought it was pretty cool I could migrate my RISC CPU design from Logisim to Verilator, and even throw in some GTK so I could display some video, and have it all just work.
My boy caught a mouse once. He really worked for it too, he had little bits of moss stuck to his nose when I found him. When I told him it was time to go inside he just shook his head to kill it and headed for the door like it would just be okay to bring it in lol. Had to pry it out of his mouth.
