Fortaleza Glasses Technology

These are the technologies that I think Microsoft should put into their Fortaleza project.

For the glasses itself:

Rather than putting a camera and a small display like Google Glass, putting the technology on the spectacle lens itself would be better. It would use less space to have a comfortable experience.

And for the wristwatch:

A great way to interact with the Glasses. Good for navigating the menu easily, to play games and to interact with augmented reality objects.

I am looking forward for this project and hope it would be a huge success. I would make 3D mock-ups of the glasses but I am not sure which program I should use. Please let me know what you think Microsoft should use in the project and also what I should use to make good 3D models.
