The source code to the kernel of google glass has been released. I guess all I need is a device now.

The project really seems exciting and I would really love to try it but call me old fashioned if I humbly believe I would probably find tiring having information superimposed all the time. That said, I have not tried it so I have no idea how annoying it can be to be wearing them long term.
