    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 Spaceweather.com. John kindly gave me permission 
    to do so and Dr. Tony Philips published it today. See 
    http://www.spaceweather.com/ 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 
    time.
