I'm slowly working on my own pairing pipeline, with keystoning for proper toe-in instead of horizontal offsetting... might be possible with SPM but I've just started to explore its features.
The big questions now are:
1) How to reproduce the 3D effect? Lenticular prints from FujiFilm for $7 are expensive, and I can't find a web site. Just ordered red/cyan anaglyph glasses and "Skweez-Vue:" viewers from the3dmarket.com to get started.
2) What to call this camera?! "W1" leads the pack; "Fujifilm Real 3D W1" is a ridiculous product name (and demonstrates why Apple is taking over the world).

The manual shows interesting features for adjusting parallax and for taking non-stereo twin-lens shots.

Perceptual experience consists of an enormous number of possible states. Previous fMRI studies have predicted a perceptual state by classifying brain activity into prespecified categories. Constraint-free visual image reconstruction is more challenging, as it is impractical to specify brain activity for all possible images. In this study, we reconstructed visual images by combining local image bases of multiple scales, whose contrasts were independently decoded from fMRI activity by automatically selecting relevant voxels and exploiting their correlated patterns.
Binary-contrast, 10 x 10-patch images (2^100 possible states) were accurately reconstructed without any image prior on a single trial or volume basis by measuring brain activity only for several hundred random images. Reconstruction was also used to identify the presented image among millions of candidates. The results suggest that our approach provides an effective means to read out complex perceptual states from brain activity while discovering information representation in multivoxel patterns.

PHOTOKINA 2008, COLOGNE, GERMANY, September 23, 2008 FUJIFILM Corporation today announces a radical departure from current imaging systems with the development of a completely new, real image system (3D digital camera, 3D digital photo frame, 3D print) that marks a complete break from previous attempts to introduce this technology.More at DPReview...

Why must every previous device be made obsolete with every new development? Why can't we value machines over lifetimes-- multiple generations-- as opposed to a few years or until the next one comes out?
I want to see a "chassis" approach to electronics-- replacing or repairing only components or subsystems to get new functionality.
The iPod Deb gave me is a good example of this-- worthless to her, a solid chassis with a bum battery and probably hard drive too. With a 8 or 16GB CF chip, a new battery, and bluetooth, it could keep going for decades.

It would be difficult to replace blue LED's with "regular" (read: red, green, yellow, or white) ones-- for surface-mount LED's and RGB ones, I'd more likely damage the circuit board... though outright removing one would be almost as good as replacing one, with the added spiteful element of having gouged its eye out for irritating mine...
Blue LED's are alienating to many people, especially those over a certain age; they seem alien and "wrong" somehow, and it's not a result of growing up with LED's of colors other than blue, but the fact that we simply do not see blue glowing things in nature. Red, yellow, orange and white are colors we know from fire and the stars-- light sources in nature-- and these have been the colors of electronic light elements until a few years ago.
We should have learned in chemistry lab to fear blue flames since they're so hard to see, and blue-lit electronics are successors to customized cars' blue neon undercarriage lighting. These are menacing associations for me, and they also evoke cheapness and cheesy after-market design.
The blue LED has invaded consumer-level electronics and is starting to make it into higher-end electronics as well, and I think it will have an overall cheapening effect on the brand images of those companies who choose to use them. It's a high-tech artifact motif like the raw polygon and aliased pixel, and I hope it will go away after we get over its novelty.

Seems like all you need to do is:
- Shoot and stitch a complete spherical panorama to get an image with an aspect ratio of 2,
- Rotate the image 180 degrees,
- Stretch the image so it's square (aspect ratio 1),
- Run Filters > Distort > Polar Coordinates..., with the "Rectangular to Polar" option.

The Wikipedia Photography Timeline is pretty cool.
Is this creepy or not, and why?

Metamaterials, also known as left-handed materials, are exotic, artificially created materials that provide optical properties not found in natural materials. Natural materials refract light, or electromagnetic radiation, to the right of the incident beam at different angles and speeds. However, metamaterials make it possible to refract light to the left, or at a negative angle. This backward-bending characteristic provides scientists the ability to control light similar to the way they use semiconductors to control electricity, which opens a wide range of potential applications.
