Hides e-mail addresses from spam bots

Users trying to contact you have to enter a code from a displayed image or click a randomly-generated square in a larger image. Upon correct input and submission they are forwarded to your e-mail address. The only client requirement is that images are displayed. Adds noise to images to prevent OCR. Limits attempts per client. Email and challenge information is stored in a server session.
