Play This: "Mountain" -- a Mountain Simulator

I'm dead serious. If you watched Her, you'll be familiar with the creator of Mountain. In his first official game, David O'Reilly sets the bar for something different -- a Mountain Simulator! Not quite a game, but more like a screensaver that's somewhat interactive, it's quite awesome. Available on iOS, Mac, Windows and Linux, it's either $0.99 on iOS or $1.00 depending on how much you want to donate. And yes, it's running in the background as I type this post. Featuring: - no controls - automatic save - audio on/off switch - time movies forward - things grow and things die - nature expresses itself - ~50 hours of gameplay - once generated, you cannot be regenerated
