This is obviously very impressive, and far better than I could ever do myself.

But I must say it bears more than a passing resemblence to the version below, first uploaded to YouTube in 2009. Including the specific appearance of the robot and the graphic design of its eyes: https://www.youtube.com/watch?v=0mWHVvKb1hM

Perhaps worth acknowledging that prior effort? (I have no relationship, just feels like that effort--with 2009 technology--deserves some credit.)
