Google Maps. We're all taking it for granted, but imagine all the edge cases, complex real-world infrastructure and data analysis that goes into mapping the streets and buildings so well that it actually works, even in small towns.<p>It's much more impressive than Google Search. Given enough compute/storage, I feel like I can build a search engine. With Google Maps, I would have no idea where to even start.
My smart light app that lets me pick any color. Being able to match the outside color temp or turn the lights red at night is awesome and it's kinda crazy to me that we can just do it so easily now
