[Cyborg] 200 laser diodes

[kristinneidlinger]

correction: I want to make a "postural" feedback suit not "postal" suit.

I had to use a fog machine with the prototypes to see the lasers, but maybe
glasses could help see the lasers too. Or maybe a wearable fog machine!

these might work:

or we could make some:

danielle's work was my inspiration:

I can share my research if you like.  Attached is a pic of the study with a
ballet dancer. He liked to roll around...
He is actually interested in choreographing something with the suits.
perhaps a collaboration?

anyhoo i'd like at least 14

thanks eric!
