The Atomontage Engine got a brief shout-out from Minecraft creator Markus Persson back in 2011, but 2011 was a long time ago. So it's nice to see an update on the project in 2013, and things are looking very interesting.
Unlike most engines, Atomontage is based not on polygons but voxels. So, think Minecraft, only in this case on a far more detailed scale.
Like, way more detailed. Not to mention more organic. The video above makes this look like something from the distant future of better video games.
The most intriguing part, though, is the hardware required; the creator says the video above is running on a notebook with specs "comparable with a decent gaming PC from about 2005".
