I would love to see a parallax feature in a premium template. I would definitely upgrade from free subscription to premium if you guys made a template with parallax.
I've made several parallax headers but only for static html. If anyone knows how to incorporate that into a joomla template, please pm me. You can learn how to make them here:http://webdev.stephband.info/parallax.html
There are only two great Joomla examples (but I know shape 5 would do a better job) that I could find:http://demo.rockettheme.com/dec08/index.phphttp://www.demo.pure-joomla.com/pj_relax_15/index.php
