This is incredible! Thanks for posting.

For me, the camera is just looking up and spinning clockwise. I tried in both Brave and Chrome.
This is the first time I ever thought we need an open source monitor hardware
Unfortunately, DisplayPort and HDMI specifications are kept private unless you're a paying member. I've successfully implemented DisplayPort 1.2 in an FPGA from specification documents I found, but I could never find the specification for anything better.

There's a husband and wife team of optical scientists who have been studying myopia and theorize that high contrast across the retina signals the eye to elongate which leads to myopia. "Their big breakthrough in understanding myopia occurred in 2008 when they studied a particular group of people who had a genetic form of myopia that’s very severe. They discovered a gene mutation that was causing the myopia." As a result, they patented glasses that blur your peripheral vision, and a trial has shown them to be more than 50% effective at reducing myopia.

I keep waiting for a commerical version of motion-tracking perspective-changing 3d on TV, but nobody seems interested in this space...

LOL, what? There are indeed 3D displays with eye tracking built in that do this. I was just at Display Week expo last week and saw a handful of new models, and they've been around for years.

The moment I saw the use of motion vectors with gaussian splats I started wondering if it was a viable way to achieve high performance, high quality spatial video. Instead of capturing from all angles like most current approaches (which seems more geared to create content that is used in place of a 3D model) why not capture from a fixed perspective, using an array of cameras covering about 1m square to allow for slop in head position, providing parallax and perspective correct rendering. I'd presume that'd make it even more compressible too, since you could get rid of any data that isn't visible from outside that frustum.
It would be a true hologram, completely supplanting 180/360 stereo video. Imagine Avatar on such a format. Or, lets be real, porn.

What do you think is on the horizon of cool or interesting within your work?
The big push is currently towards microLED displays because of the high brightness and fast modulation speed. Yield is not yet good, and there's difficulty in growing all colors on the same substrate. Picking and placing different color LEDs onto the same panel is not cost effective. Red microLEDs are also not yet as bright as blue and green.
There was a push towards micro liquid crystal panels with laser illumination to create holographic images with depth. There are several startups still pursuing that, but the image quality isn't very good at the moment.
The latest advancement has been in the optics with moving to pancake lenses to reduce the length of the optical path from the display to the eye. The Meta Quest 3 has a smaller form factor than previous generations because of this.
You seem to know a lot about this. Have you worked on similar things?
I work on VR/AR headsets where there's a drive for higher refresh rate displays to do things like multiple focal planes with the extra frames.
Another idea: why not put a tiny TFT display on the motor? You can get cheap ones at aliexpress.
Standard displays are 60 Hz. You need a much higher framerate because not only do you want 60 frames a second, but you also want some number of frames per angular rotation. For 1° of angular resolution, you would need: 360°*60 Hz = 21,600 Hz display. Liquid crystals can be modulated at KHz speeds, but you're not going to find associated driving circuitry to do that. It's not easy, and there's no demand for it.
A TI DLP DMD can modulate at those high speeds, and there's readily available driving circuitry for it. However, it's a small reflective based display designed for projectors, and you would then need a light source to reflect off of it.
MicroLEDs would let you increase your pixel pitch with fast modulation frequency, but the display area is still small at the moment because of low yields. You also need a custom chip to drive the microleds at the required high framerate.

Ended on a hand of: K J A A Q and did not receive the Jacks or Better $1 payout. According to a brief search about the rules of video poker, a pair of aces is considered better than a pair of jacks.
