With the latest firmware making sound, could you do a waterproof version of this?
Would allow you to see speed and hear sound

Are you showing how the GPS could be attached to the ear?
If so, you probably dont want to do that -> your head has water in it, with the GPS that close to your head, it will affect signal reception.
nice idea - though I'm not sure how you can see it too...
