[guardian-dev] Pixelknot

[Harlo Holmes]

Hi Bernard,

Thank you so much for doing some beta testing, and for posting it to
Vimeo-- it was thrilling to see someone else use our app, and really
instructional for me as a developer to see how others naturally interact
with the UI.  Would you mind doing it again for the build posted here:
https://github.com/guardianproject/PixelKnot ?  (And please let me know if
you can't build it-- we can give you a precompiled apk)

Thanks,
Harlo
