wow! thanks for your contributions. :) would you mind giving some background on how LiquidFun came into existence? is it a 20% time project, or a weekend thing made by Googlers? was there ever a business case for it?
VoltAir was the game where we wanted to showcase a few new technologies: how to build a game using tech other than Unity (which still dominates mobile game dev), first party Android TV and controller support examples, and of course LiquidFun which also powered LiquidFun paint.
The longer term business vision was what you now know as Stadia which evolved from Chromecast and Android TV experiments like these.
