Flash seems to be broken on FF5 (on WinXP). The video doesn't move though the sound plays fine. Or the video shows a couple of frames as the cursor is moved.
Unclear how you could photo-parrot that, though if you have enough hours..
OTOH.. a cat who figured out how to deal with a doorknob--leap from nearby appliance top and rotate it, en passant
--is yet another specimen of undiscovered talents we presume couldn't be there. Seems there're lots more than 'signing' apes, all around.
