I challenge someone to find an automated response to C/R.
Students at Berkeley have already beaten the C/R system setup by Yahoo! and with a selection of 191 different version of text obfuscation they were able to return a 92% success rate. In much more detailed images, with random background textures and overlaying text they were only able to achieve a 33% success rate but I am sure with time they would be able to do better.
In a paper published by Greg Mori and Jitendra Malik they explain the methods used to defeat the system. For the full write up you can visit their site on Breaking a Visual CAPTCHA
