Sony Mobile updated the Xperia Marshmallow Concept to the newest build yesterday (read here). In amongst the changes is an updated home launcher with build number 10.0.A.0.4. As well as now allowing you to uninstall/disable most preinstalled applications, one change we didn’t notice yesterday was the ability to change the icon appearance.
A new option in the Home settings menu will allow you to use Framed, Glass or a Round icon appearance, a nice additional customisation option for those that like to tinker. See the difference between all modes below.

Not all of the icons here are changed, only the five listed below left. You can see how these compare to the default setup at the bottom.
