These visuals for Sha-256 are great for noobies looking to mine, get bitcoin, or do there own stuff. I found a fun project is to try out the same input each time and watch the hash come out the same. Thats how hashes work, they are used by putting the block_header in the hash and seeing if someone's hash comes out below a target. If you have the same block_header, you'll get the same hash. You could say the block is arranged numbers; the hash.
