there are no questions. the kittens are merged into an image that functions
like an image map. the robot would be guessing co-ordinates, not
combinations.
the idea is that the robot is going to have to actually recognize kittens in
the image
(from among other animals) and send the server co-ord
Here is the complete list of characters that I am currently using. I
basically removed more and more over time as I experienced entry
failures. They seem to be pretty workable using these characters:
private static final char[] CAPTCHA_CHARS =
"abcdefghkmnoprstuvwxz".toCharArray();

The trouble is that the answers to the kitten questions usually have a
small number of possible combinations: 1 - 5 roughly so on average a
robot may be successful 20% of the time.

I realized that it was a third party thing. If it was written by the
wicket devs it would rock like everything else they write!

i hope you guys realize that this isnt a wicket issue, its an issue
with the captcha lib that wicket uses - thats what is generating the
image. so why not simply integrate a different lib into your own
component? possibly submit that as a proposal to replace the current
one...

Good idea! I tried throwing out all the letters and using only numbers
but
It is still pretty nasty in the 1.3 series. I got around the issue
somewhat by throwing out several letters that could be indistinguishable
after deformation. Things like "h" and "n," "I" and "1," and "t" and
"f." But yeah, about 10% of the time, they get pretty bad.
