1st edition:
1. (5/16) there is an incorrect URL for 3-D Space in the Resources section at the end of the book. This has been corrected above, but again the correct URL is: http://www.3-DSPACE.org. 3-D Space is a non-profit arts organization dedicated to the preservation of the history of stereoscopic imaging and the advancement of current and future 3-D arts and sciences
2. (5/16) on page 1 (and mentioned again on page 4 in the 'Fun Facts' section), it is actually Oliver Wendell Holmes, Sr., father of the famous jurist and Supreme Court justice, who invented the stereoscope and made it available without patent in order to benefit the world... early open source!
