I would like a return of ghetto blasters. Those things are cool and I have one wired up to an ipad cut into it to play tunes.

I have a google glass too and I don't wear it so much in public. You can't really see it with a hat - probably mounted in real glasses and long hair or a hat is best.

I'd hold up for the contacts over the eyes, this is sort of a half step that will be great proving ground - but ultimately too invasive into life - like at a partttty!
