3D Captcha Problem for Blind

Recently I noticed new form of CAPTCHA used by YUNITI at the registration page .

http://www.yuniti.com/register.php

The screen shot below shows the CAPTCHA used by them . The user while registering on the website have to match 3D images of objects shown .

For example in the image shown below Guitar , Apple and Table Lamp images have to be matched in sequence with the images shown.

3D CAPTCHA are clear problem for users with Visual Disability along with people having learning disabilities.
