TextPaster that rotates characters randomly 360 degrees

I have created a TextPaster that rotates charcaters randomly 360 degrees. If a character is between 90 and 270 degrees it will be underlined. This TextPaster also places the character at a random height (like the NonLinearTextPaster). I thought maybe this TextPaster can be used in JCaptcha.
I have attached the source code to this issue. You can see the captcha in action at http://smsdudes.com/captcha.htm
Any feedback is welcome.

Cheers
