me too, what are the sources for those other two you mention?

David O'Reilly's work is primarily animation unlike this.

oh dear!

If prior art involving intentional i-frame compression artifacts is all the evidence needed for claiming plagiarism here, then David is "guilty" of it as well:

tatjanamarusic.com/flash/woman.html
(2003)

(Not a slam against David, I love his work. Just not a huge fan of bickering over technique "firsts"... it seems like no matter how far back one can dig, there's always some obscure person who did it far earlier. In this case, undoubtedly there's plenty of people who were there even before Tatjana, but I'll leave that to someone else to find.)
