Perhaps one can look at this in a more positive sense?
Though I'm no scientist like Newton or Hawking, or a great advancer of society like Gandhi or M.L. King, indeed, I'm a miserable failure when compared against the highest standards of humanity, and infinitely more so when judged against the perfect standards of God,
the Good News is that even I can receive all the greatest benefits of eternal life through grace, rather than the consignment to nothingness that I deserve by my own efforts.
Camera flashes won't work too well; although they are very bright in the visible, they don't put out much IR (most of their light output is weighted towards the blue end of the spectrum). IR LEDs, or, even better for high-intensity pulsed work, an IR diode laser, would be much better sources.
While I highly disapprove of jackasses who like to run red lights, I don't like the idea of a pervasive surveillance society any more. I'd prefer if, rather than speeders using such technologies to personally get away with reckless driving, civic-minded people would set up blinding LEDs/lasers in a permanent location near the cameras so they will be disabled for ALL cars.
I remember a 3-volume set of books called "The World of Mathematics" from when I was around high school age. The books were a collection of short essays on mathematical topics by current and historical mathematicians. The subjects were very wide ranging and quite approachable. Those books greatly contributed to my interest in mathematics (leading me to a double-major in math and physics). I don't know if they're still in print, but they're worth tracking down.
Last stanza: consider the || separators between trinary digits |, | |, | | |; decode as for first stanza, gives: tadcfmtt blaztr zyppt pioqttb -> "employee number basse sixteen"
thus, the central numbers are probably the employee # of the prank letter writer. Someone at Fermilab could probably check this (maybe Frank Shoemaker?)
DLP works because you can fool a human eye into seeing a quickly-scanned point of light as a continuous image. Freeze a point in time, and the DLP is projecting a single bright point of light focused in one place. It's not practical to reverse this for taking photos, since the light coming from real-life objects that you want to photograph is usually coming from all points on the object at once. While you are scanning around the object looking at one small point at a time, you are wasting all the photons coming from the rest of the object. To most efficiently use the light reflecting from a photographic subject, you want a sensor that can simultaneously record the light coming from all points on the subject at once --- e.g. a CCD sensor at the focal plane of the camera, just like we have now.
The idea of a scanning, DLP-like camera isn't without merit. One could imagine a futuristic replacement for flash photography where a set of colored lasers are scanned across the subject at high speed, and micromirrors guide the reflected spot of light onto a single-pixel sensor. This way you can record both color reflectance information and 3D topology using a much more simple and compact sensor system than current CCD cameras. But in order for this to work, you have to be providing the illuminating light yourself, making sure that it is focused on the one small spot that you are currently scanning. Such a camera would be horribly inefficient for photographing any "naturally" lit scene where the illumination is spread over the entire subject (e.g. a sunset or a diffusely lit portrait).

I think we've solved it!
