Really nice, haven't figured out what it's capable of, but reminds of a similar interface I wrote from scratch about 15 year ago in Java Swing. Blows me away how powerful browsers and JS have become. Really amazing that you can do this with so few lines of code, compared the (tens of?) thousands lines I wrote to do similar.
