We're expecting to hear much more on Android Wear and the first smartwatches to showcase it — Motorola's Moto 360 and LG's G Watch — at Google I/O later this month. But before the developer conference kicks off, Google is today offering another brief look at the two devices. They're featured in a dev-focused blog post that goes over just how easy it is to build apps for both square and round smartwatches.

"Designing for Android Wear is pretty different from designing for the desktop, phones or tablets," said Roman Nurik, who worked with fellow Android Wear design "advocate" Timothy Jordan to mock up a walking tour app. "Working with constraints involving scarce resources like device size and user attention means it’s more important than ever to think deeply about your ideas and iterate on them early and often."

This is one of the first times we've seen a real live Moto 360 with the screen on, though admittedly there's not much to look at here. Google is no doubt saving the best of Android Wear for I/O, which starts June 25th.
