Being blind makes you helpless

[atomic1fire]

I think it might be silly or amusing if genetics could give an echolocation mutation that either relied on blindness or a blind fold, but at least let you move around freely because it showed walls and doors. Maybe even false walls because they could sound different. It could probably even faintly show when the power's down. (since presumably it could work like drone vision, only it shows shapes for things you can't walk through rather then just shapes for humans.

Basically like a genetics version of mesons.

Blindness as a whole kinda sucks though.
