CSS Effect: Hover Glass Reflection, Drop Shadow From Dawn Demo Collage

[xofonno]

Hello,
I would like to mimic the exact effect of what is happening in the Dawn Demo Site for the Collage Section with bags shoes etc. The main image does a really cool enlarge, drop shadow and then a shimmer of a glass reflection at the end. the others produce a drop shadow and bulge on hover. Can someone point me to the CSS and some basic instructions on how to implement this in my Dawn theme?
