I just looked at this iPhone alarm clock on Gum Road, which I also read about on HN. The page describing the clock is janky. Slowly scroll down the page (with a track pad) and it will jump up and down erratically as you get past the "Add to Cart" button. Hover your mouse in one vertical position on the page and it will turn the header on and off over and over again.

Maybe I'm a Luddite but I just get the feeling that we've gone very wrong in our over-engineering.
