Didn't read the article, design was too distracting (mouse wheeling with the mouse over the left side does NOT scroll the page). But check out that scrollbar!
::-webkit-scrollbar { width: 10px; }
::-webkit-scrollbar-thumb { border-radius: 10px; background: #ddd; } Thought it must be JS but it's webkit stuff. Can't decide if silly or nice, but I think it's pretty nice.
