DIY project: Car Dash Camera Mount

I've not posted a DIY film tool link in a long time, but the Car Dash Camera Mount listed in this morning's "Weekend Builder" email from Instructables grabbed my attention. If you need a way to film yourself (or someone) straight-on while driving, this could be pretty useful. Unless, of course, you're using a big-ish or heavy camera... in which case you probably can afford to rent the "proper" tools.
