What is it?
Here's another clue:
It's nowhere near finished into a working camera, but the array part is done. It's a newfangled contraption that I done dreamed up, the basic idea being a diverging pyramid of thin light pipes, each of which captures a narrow angle of view and directs it to a specific spot on the film plane. Unlike a glass lens, pinhole or other refractive optic, the Light Pipe Array doesn't invert the image at the film plane.
The background story on this is that I had purchased several packages of these thin, black plastic stir sticks (which I could only find at Target stores), to be used in a now dormant upgrade to my Pixellator camera project. But looking through a cluster of these sticks one day, and seeing a somewhat coherent image, my mad scientist's brain began to churn.
Here's a blog article with more details.
Now that I've posted this, I have further incentive to finish it and get some paper negatives (or Harman DPP) exposed. And I have no idea what the shutter speed will need to be; it might require a sub- 1 second mechanical shutter, which should be fun, considering the size of the array (the front baffle being over 8" square).
