Here's the finished product: desktop functionality when you're at home and easy portability when you need to go.
I angled the foam to pitch the laptop forward, however, I've since found that this isn't ideal for dissipating heat. If you lean the macbook all the way back but leave an inch or so clearance between it and the wall, it runs cooler than sitting on the desk.
Again, if I had it to do again I would leave the frame on the port side and trim out the mesh. Also the optical drive isn't accessible under this configuration without lifting the macbook up slightly. However, this happens so rarely that it's not been work developing a better design.
Enjoy I'd love to hear/see how you implement/modify this idea.
