No lights.
No sounds.
I had an idea that would make life so much cooler.
What if you could remove your ear drums and replace them with digital ear drums?
(update 12/6 -- turns out somebody did)
Then you could have settings for really convenient things like mute, volume control, and noise filters.
People being too loud? Decrease volume.
Someone listening to awful music right next to you out loud? Mute.
Don't like someone's voice? Change to robot.
Ahh... maybe one day.
Would you give up your real ear drums for digital ones?
