Binary data visualization
Really cool, I really like that binary data, with all it's abstractions, still creates visual meaning. Also reminds me of pixid [1], which sadly never got any traction on HN. Plus the common example, in which CBC encryption fails [2], is definitively something to throw in.<p>[1]: <a href="https://github.com/FireyFly/pixd" rel="nofollow">https://github.com/FireyFly/pixd</a>
