At the tail end of today’s Google I/O keynote, the company demoed Google+ Events, which, as you might imagine, let’s you invite your virtual buds to an in-person hangout. You’ve probably already guessed that there’s some pretty tight integration with Mountain View’s other virtual properties, including Calendar, which means that sending your friends or coworkers a “save the date” to brunch or brainstorming no longer requires clunky email, or a phone call. That’s not to say that your contacts need to opt-in to the search giant’s social networking site to join the fun — email invites are still available by typing your friend’s address alongside your circles, or individual friends should you wish to plan an awkward inter-group soiree. You can choose from a variety of themes for your e-vite, which integrate motion or static banners. Once the fun begins, you can hop into Party Mode from your mobile, and photos you shoot during the event will appear beside the invite — friends can add pics to the page as well, which you can later download. For now, please accept our invitation to jump past the break, where a Google demo video awaits.
