Computer Logic Gates in Minecraft (Only Redstone and Torches)

This is a video of me building and explaining Logic Gates and how you can literally make a working computer out of an input, line of redstone, block, and output. And there is a challenge as well seeing if anyone can build a working computer out of nothing but these blocks. If you ever wanted to know about computer logic than this is the perfect video for you.
