After working out a PopSocket interface that I liked, I created a couple of things utilizing it.

This is a stand to hold the phone at 15degrees. It is dimensioned to fit my smartphone with a Popsocket on the back. I love the ability to easily rotate the phone for portrait or landscape with access to ports and buttons.
