We do a similar piece of software that tracks your face movement: it's free, and you can get it from

Install (Windows only), run, position your head facing ahead at the webcam, and then move the mouse around by turning and raising/lowering your head. There are two versions, one that click automatically when you stop moving your head and one that doesn't (so you can use another dwell program of your choice.)

evolution by definition increases the survivability of the species.

That's not correct. Biology is full of species that have evolved to fill particular niches, like the panda or flightless birds on islands. When the niche disappears the species becomes extinct. So evolution is perfectly capable of reducing survivability, depending on the timescale you're measuring and the area you're studying. Generalists survive, then specialise into the new, vacant niches in their local environment.

Looks great - to me, with good vision. But can't Slashdot seize the opportunity to improve the accessibility of the site for blind fellow geeks?

Looking at the HTML, here's two really simple things that would really help:

  1. A skip links link at the very top of the page code: there are long, long stretches of forms and links to plough through if you can't see the main content in the center of the screen and have to go through it line by line.
  2. Use the LABEL elements properly: they're not for layout as such, they're for indicating what bit of text is associated with with form element. They're used in some places - but they're broken! What's the point of getting rid of tables ("They're, like, confusing content and presentation!") and then using broken CSS (FIELDSET elements with blank LEGEND child elements and unattached LABEL elements used, erm, for presentation)?

I develop a free web browser for blind people called WebbIE) but I think these suggestions would help JAWS and WindowEyes screenreader users, IBM Homepage Reader users and everyone with non-visual browsers. How about it? Show everyone how it should be done!

The sooner you fall behind, the more time you have to catch up.
