This is how we do outreach.
I set up the Vespera just behind the dance floor at a small trance festival last weekend.
Displayed live stacking of various objects (nebulae, mostly) on my phone and tablet.
(Tried to put the image onto a projector via Chromecast, but Chromecast doesn't work
unless there is Internet access so it can log into Google. Worked fine at home, but not there)
