Plexiglas is a very cool material, a clear, tough plastic that can be used for a variety of projects from see through cases, to a pseudo blast shield, to the tripod I will teach you how to make. While it's not technically a tripod it serves some similar purposes. By itself it can hold the gopro on top to gain a little more height. The gopro can also be hung underneath if you are trying to show how to repair something on a car and the plexiglas will protect the camera from harmful slag while welding or grinding. Also with the new wifi live view function through wifi on the Hero3 cameras the "tripod" can actually be used as a cover over the gopro that holds your ipod or phone on top.
