youtube minigame while your video loads!

So I'm stuck on my low bandwith tether connection to my phone, and youtube videos don't load so quickly... and i was going to start reading a few comments, and hit the arrow down key... actually, I held it for about 1 second when I noticed that I was controlling the formerly spherical loading splash screen animating icon!

Its that centipede game where you collect dots, and it aids to your tail. Neato!
