iCaptcha

Captcha is a method of telling the difference between humans and machines by using a distored image and asking the user to enter the corrisponding text into a textbox. There are many different implimentations of Captcha's on the internet some more secure then others. This code that I have uploaded is by no means the most secure type of captcha out there, it's main purpose is to show how a captcha system could be created with little effort.
