Who ever said that Google can't release odd little apps too. Maybe it will work, but mostly, its a look at what the tech can do and how their minds can be as stretched as those random start-ups you sometimes hear about on Kickstarter. 

Sprayscape is interesting. I've played with it, and it is a quirky little tool that allows me to show the world around me, and blank out bits I don't want to share. I'll be using it more I expect, if I remember that its there. 

But Google Creative Labs is great. Going in interesting directions and bringing us along for the ride.
