    Since today is the day that the first piece of the Cosmos 2251 and Iridium 
    33 satellite debris was predicted to reenter the earth's atmosphere, I 
    decided to use a fresh KML file supplied to me by John Burns to create a 
    stereo pair and send it to John kindly gave me permission 
    to do so and Dr. Tony Philips published it today. See if interested.
    Thanks John, and Tony!

    Do to cuts, as of this year I am substitute teaching (rather than teaching 
    just science). One great thing about subbing is now get to show my 
    hyper-stereo 3D images - like the one just published - to new kids all the 
    time. "Everything looks fake!", one student said. Whole cities look like 
    perfectly detailed models just meters away.
    I create this "Lilliputian effect" by spacing my ordinary camera in two 
    positions (the baseline), one at a time. If the nearest part of the subject 
    is one or more km away, I often use a baseline that's several meters long. 
    When the pictures are viewed two at a time, the person perceives what they 
    would see if their eyes were as far apart as the camera positions were. This 
    gives them a giant's perspective!! The kids always love it.
    Decades ago I tried to capture a meteor in 3D but my baseline was either too 
    long or the meteor was traveling at a tangent to our positions. It didn't 
    show depth.
    This last Halloween night, for fun, I set up my stereo equipment outside on 
    a table for the kids to see after I gave them candy. One parent even went 
    home and got her husband so he could experience the effect too. The first 
    image I showed was a stereo pair of my neighborhood I shot from an airplane. 
    Two Halloweens ago when we ran out of candy I dragged my 8-inch scope out so 
    the goblins could gaze at the moon. One kid said, this is better than candy! 
    Most had never looked through a scope before. I'll never forget my first
