Bitcoin Network Status Display

The current blockchain tip block hash is expressed in binary with its colors derived by the hash itself. As transactions are added to the mempool, the top half of the screen fills up and changes color. Recent blocks tick around the outside of the clock face, filled in when a wallet transaction is confirmed. Difficulty adjustment and halvening cycles are drawn as progress bars that grow and change color.
