I loved that one. We spend an entire year on high school programming the 16F84 on assembler. We re-implemented all projects we did the previous year with nand gates like semaphore, infrared barriers for counting stuff etc with pics, and it was mindblowing for me. I also remember we did a board for writing the program in the pic because it was too expensive in my country.
