I believe we tuned the interpupillary distance (IPD) down a bit for the demos at PAX. The IPD is a software setting that changes how far apart the two stereo images are drawn from. If it's set to a distance larger than the actual distance between your eyes then you'll perceive it as very strange (each eye seeing a different thing that your brain can't unify), and it will be very uncomfortable. If the IPD setting is set to a distance less than the actual distance between your eyes then you won't perceive as much depth when looking at it, but it's still fairly comfortable. The extreme version of this is just looking at normal monoscopic images (e.g. watching a movie) - perfectly comfortable, but no depth perceived from it. Rather than adjusting it for each person we gave the demo to, we set the IPD a bit low so that it'd be comfortable for everyone, but people with a larger physical IPD wouldn't perceive as much depth. Sorry you felt let down by it.
