Halo levels and maps in VR, via Neos.

[VAMatt]

I was browsing Facebook a little while ago, and came across this video. Apparently, some people are building virtual reality Halo levels in Neos, with the goal of making it playable at some point. I was vaguely familiar with the existence of Neos, but this is the first significant stuff that I've seen made in it.  I think it is incredibly cool. 

I assume there's other cool Neos stuff floating around.  Does anybody have any recommendations for stuff to check out?
