The device has "285 microspeakers emitting ultrasonic waves that hold up the light, and have a frequency inaudible to the human ear, allowing Luciola to operate in apparent total silence".
Yeah, but how does it affect the rest of the natural world? Just because it is silent to us doesn't mean other forms of life can't hear it. I'm reminded of the damage our submarines are doing to whales and other sea-life blasting away with powerful sonar. How would these sounds affect animals that can hear in the ultrasoni
Another step toward Vinge's locators.
Equipped with movement or temperature sensors
Wouldn't that increase the weight of the thing quite a bit?
to deliver a message
Wouldn't the needed hardware also increase the weight of the thing? Except, I suppose, if they transmit by light pulses.
Anyway the thing is impressive, but as with many impressive things, practical applications may be elusive.
Reminds me of the TV show Revolution:

If we ever make clanking replicators [wikipedia.org] the prototype must called Weird AI Clankovich.
