I agree. The library and visualizations were great, but the demo page can take some polishing still. I really didn't understand that anything I did on the page (scrolled down to read more text, clicked the left/right arrows under one of the illustrations) was going to affect my browser history, and was puzzled when I failed to get back here with a single click on Back. Very surprising, and actually quite annoying.
