Hello.
CAPTCHA tests are indispensables. The problem comes when you *only* use
visual tests (such as "visual turing numbers").
If you need CAPTCHA tests, you may use them both visuals and audibles.
This is a good example: https://www.e-gold.com/acct/login.html

Hello, Clive.
Depending on the target of your website, you shall need to keep in
mind the (in)accessibility of this kind of tests:
http://www.w3.org/TR/2003/WD-turingtest-20031105/
right and almost 3 people on the planet care in practice.
besides the chances are the blind person in question will not be able to
navigate through your sea of nested tables. (have you ever heard
a screen reader walking thru 5 level of tabel nesting so that you can
be told of the lovely logo image that the nested tables are apparently
positioning ... fantastic
oh any then there is the problem of inaccesibility of mailboxes
(because it's full, overloaded, etc) because every spammer and his dog
can write
an automated mailing script that uses your webform if you don't stick some
sort of CAPTCHA in there...
the most inaccessible on the web currently is the 'look how clever we
are' language
and document structures used through out the W3C site - bloody
impenetrable.
pot calling the kettle black.... so what if every user agent under the sun
can 'read' the W3C site - *I* can't read it, fat chance my browser will
be able
to explain it to me.
given that 9 out of 10 government buildings worldwide are not even
accessible by
wheelchair users (I didn't do the research but I'm willing to put some
money on it)
worrying about inaccessible webforms is maybe a little premature.
-------------
and given that we, in the west (at the least - I don't believe asians,
arabs, whatever
are any nicer) are a bunch of body facist hate mongerers - your
television and billboards
are telling you that if you have a disability (that includes being ugly)
then you
should be figuring out how to get the f*** off our Calvin Klein planet
....
or put another way - is there a good reason why the web should be any less
discriminating than the rest of society.
<rant>
By the way, AFAIK they are also known as "turing numbers".
Regards.
