Is the ReCaptcha "customization options dictionary" JSON?

This is something of an embarrassing question to ask, seeing as it is mainly about my lack of Javascript knowledge. Seems like it might be "so obvious" that nobody specifies it anymore.

Recommendations for java captcha libraries

How might I design a system similar to reCAPTCHA?

I'm fascinated by the CAPTCHA system used on SO... I would like to know more about the "many factors" which make reCAPTCHA work.

Multiple reCAPTCHAs in one ASP.Net page

Hi, It is possible to add multiple reCAPTCHAS in one form? I tried doing so, even giving the multiple reCAPTCHAS different IDs, but when I load the page in the browser, only one of them is shown.
