Anyone know where this rabbit hole leads? topic

I just got my Xperia Z3V yesterday and I started messing around with it. If you go to Settings > About Phone > and click on the adroid version multiple times it will take you to a black screen with a big number 2. Spin the 2 clockwise and it will take you to a Red Android logo screen kind of old school looking. Press and hold in the center and it will take you a screen with all the little adroid icons bright colors and when you tap them they move. This is as far as I have gotten with it. I was wondering if anyone else has found this or was able to get past this step. I feel like there is something more to this.
