Ray Harryhausen created and left behind such a huge legacy - not only in his work, but in the vast number of people he influenced and touched. I count myself among them, of course. There's so much to dig through, don't leave it to Wikipedia to inform you - drop by his site: http://www.rayharryhausen.com/index.php and you'll get so much more.
As for the tribute - here's mine - a piece of artwork that I created. Thanks Mr. Harryhausen.
