NASA Stereogram

I just made this for fun today- it's a stereogram made up of all the names of NASA astronauts, as listed on Wikipedia on April 7, 2011. They read in columns; the leftmost column is unaffected by the stereogram, so you can read all the names. Now, use the wallpaper method to view the stereogram (that is, not the cross-eyed method) and see what you can see :)

If anyone's interested, I used Excel to pare down the copied list from Wikipedia, then ran a custom AutoIt script I made a year or so ago for creating ASCII stereograms. Finally, I copied the text into AutoCAD so I could have ultimate control over the character width and spacing, and exported as a .png from there.

ASCII stereograms are fascinating to me, since you can actually analyze it and understand how your brain makes it work. The fact that your brain processes the anomalies to assemble a 3-d image almost instantly, is just stunning to me. What a design!

Edit: Here's another one- same basic process, but I made up a more intricate pattern this time. Just in time for the 50th anniversary of manned space flight and the 30th anniversary of the first shuttle launch!
