The font matrix is actually interactive. Now about UX: I had a brain-something when I first scrolled past it... it seemed some fonts changed weight... but I couldn't understand - is it my eyes going wonkey when some char is closer to monitor upper edge rather than lower or what? I scrolled again and again and again, trying to parse whether my eyes are OK or my eyes don't like that font and kind of didn't notice anything... then few more times, by spending at least half a minute trying to figure it out. I figured: they are being changed automatically! I thought: It would have been better to design some kind of carousel, so I can switch between modes. I revisited that page after reading HN comments and then noticed that mouse pointer is actually changing weight and width... doh.
