I just recently saw a very creative application for Glass that allows queries to WolframAlpha - but it's not a "native" app.
I'd like to assist / dev a native (if it can be done on RaspberryPi, Glass can handle it!) Mathematica OR WolframAlpha app - speak your compute query, it hits the cloud - boom.
Existing "alpha" app obvoiusly listens to voice query, sends to server, then sends wo WAlpha, then return.
We can skip a step here
