[url=http://en.wikipedia.org/wiki/Captcha]What is a Captcha?[/url]

I thought it would be entertaining to start a thread so users can post custom made captchas. I just started learning the [url=http://us.php.net/gd]GD library[/url] in php so I can toy around with Captchas.

These are very useful in fighting spam bots and will be used in my [url=http://www.syntax******.info/chat/]Community Forum[/url] which will be launched at the end of this month.

Check out my first one: [url=http://www.syntax******.info/_test/mycaptcha.php]Captcha[/url]
*6 characters, 6 dice = Each dice represents the correct characters position on that row

So yeah, show off all your bad ass Captchas here.
