Ricky mastering the lights

Ricky is making great progress with his Hub!  Over the weekend he has become a master of the lights and now we're on to Challenge#6--responding quickly.  Now that he has gotten the hang of the game and isn't so bent on gutting the Hub and anything he thinks is part of it, I've gone back to elevating it as, being a leggy Greyhound, he does find it a bit difficult to keep repetitively reaching down all the way to the floor.  Having the Hub elevated also seems to encourage him to actually engage with it rather than sprawling across all the buttons.  It makes it easier for him to approach/retreat as when he is too close (like when he was lying down next to it), he would have difficulty seeing around his nose to actually observe which lights were illuminating.
