QapTcha jQuery Plugin
Wow, sometimes I find a neat plugin that just makes sense. This is DEFINTIELY one of those. CAPTCHA’s are a pain in the ass. This one, however is simple and effective. What could be easier than just swiping to allow access to the form. I’m definitely keeping QapTcha in the webdev toolbox, those guys did it right!
