Theremin Based White Cane   (+9)  [vote for, against]
Compatible with Grogster's Attachments for His Cane

Rather than having to come into physical contact with the grubby world, this Theremin based cane provides a progressively louder tone as you get closer to an object. Different pitches could help the user differentiate between objects of varying consistencies.

I'd suggest pitch for proximity, timbre for texture/consistency and loudness for size.

...and then you post this.

Careful wandering around my head like that, you can get lost in there you know?

Sounds like a Disney re-make of See No Evil, Hear No Evil (linky).
