Captcha has always been an interesting thing. I understand the need for it, yet as bots get smarter the captcha programs also try and get smarter. Unfortunately, that leads us to a very hard to read (even for a human) image. ReCaptcha has a .NET API which I have used, but even ReCaptcha is getting hard to read. I thought about doing a math equation captcha (kind of like the goggles that gmail has), but I wanted something nice. I came across this really cool idea! It needs some work as it does not work in all browsers (chrome) and it also probably needs to randomize ids somehow.
The idea though is very cool :)
