This is NOT live ... and its pretty easy to see why.
Repetition of the same moves. When moving between moves (eg from idle to an action) the chicken instantly moves a bit ... and it could not be lag.
But it is quite impressive really. This guys recorded a bunch of things and assigned words to every action. Then when a user types something in an engine examines the content and finds the action "it must be".
Very weird, but cool anyway ... and original ... havent seen anything like this before ...
