This looks pretty incredible! I was initially slightly sceptical (3D printed glasses, slightly conceptual looking design), but reading what they've accomplished so far pretty much eliminates that scepticism. The project founders (Jerri Ellsworth in particular is a huge name in electronics) bring a lot of credibility as well. I'm looking forward to seeing where this goes! Hopefully they can raise enough money.

Jeri has a more detailed and technical video on her channel that goes more in-depth than the Kickstarter video: http://www.youtube.com/watch?v=cc2NQVQK69A

I'm glad they have a separate package just for the tracking system. I listened to a podcast with Jerri that was posted here, that I can't find at the moment, where she discusses the details of the work that went into building the ASIC that performs the positional tracking, and I see tons of potential for this in other projects as well.

What I like best about this is that it lends itself to 3rd-person vantage views, and static fields (overlooking a map, looking into a box, etc) which tend to be more comfortable AR & VR than trying to track/render a first person view (oculus rift) at 60 fps == less "VR sickness".

Walk me through how multiple users are looking at the same screen. Isn't everyone projecting 2 images of their own? Are the polarized glasses really narrow band, or something?

How does this compare to Oculus Rift in terms of cost, quality, and potential to be a "game changer" as everyone calls both? Especially since CastAR can be both AR and VR, could one hook up a CastAR to the games and demos we already have for Oculus Rift?

I love it, I'm in!
