Author, if you're reading, a really cool thing would be to create a small array of these cameras (4 of them) side by side.

The very wide baseline should allow you to enhance/deepen the refocusing effect and create a wide format image. I've always wanted to do this.

You can also extract depth information from each cameras lens array. In theory, if you combine that capability on a per camera basis with photogrametric and/or stereo imaging techniques, you should be able to get a fairly refined depth map of a scene passively if the scene is static or you have well synchronized shots. Something I also wanted to explore but never had time to do.

At the time, I always considered passive ranging to be a potentially more valuable feature of lightfield cameras more so than refocusing images.

There is software to make point clouds and such from the Lytro

I take stereograms with a Qoocam Ego, I have thought about getting a medium size Lytro, (the one that looks like a DSLR.)

My point was that the depth information increases with greater stereo baseline (distance between lytros in this case).

Depth maps from light fields were a topic Disney Research was publishing on while I was there. Great stuff, highly recommend checking out their siggraph paper.
