Hi,
I stumbled upon http://www.kettletime.com.au/chance where the user needs to drag and drop a box with a number into another box to prove that he is human.
How do you implement this? Any free library to do this?
Thanks

I suggest using jQuery library with jquery UI official plug-in. Here is a demo and code:

You should take a look at JqueryUI. The have a direct drag and drop implementation.

It appears to be this one: http://www.webdesignbeach.com/beachbar/ajax-fancy-captcha-jquery-plugin.
How do you implement this?
Of course, you can implement the functionality on your own (see other answers), but this plug-in seems to be highly configurable :)
Any free library to do this?
Yup, see link above.

@portoalet Personally, I find it problematic that you cannot submit the form with keyboard-only interaction.

Are you using something like mouseless browsing plugin for firefox, for your browser? I suppose you prefer the captcha alternative that asks question like "what is 5 minus 1"?

@portoalet No, I just enjoy using the `<tab>` key to navigate through input fields ... and being able to input all information (including the answer to various captcha challenges) using the keyboard :)
