Ralph McQuarrie, the legendary concept artist behind the original Star Wars trilogy, died last night at the age of 82. Here's a quick reminder of the sort of imagery that came from his imagination. Just consider the workflow between a typed page of script and a finished frame of celluloid and it's clear how important this man's contribution was. If you wrote a list of his artistic achievements, it would run right around the block and be crammed with items like "designed Darth Vader". A true sci-fi legend, his impact will be felt for generations to come.
