No, I just spent ages doing some funky things to make my captcha interesting rather than just another annoyance - this is a thread about annoying captchas, I'm quite proud of mine and was looking for some feedback to reassure me that spending time to make a good captcha was in some way worthwhile.

Just to explain what I mean by funky things - the captcha uses as its background a randomly selected square from any of the hundreds of images in my gallery. Furthermore, I found that by doing this you'd often get a very boring patch of image, so I wrote a clever algorithm to make sure it selected an interesting part with lots of detail. The font is then overlaid in a way that is nicely readable to humans whilst being sufficiently hard to OCR that I've had no problems with spam. The captcha also uses an amusing dictionary so if you click the refresh button a couple of times you'll often get an amusing pairing of word and background image.

I apologise if you consider this advertising, but I would hope to draw traffic to my website on the strength of my content, not my captcha.
