My dad passed THIS along to me (he knows how to keep me entertained for hours on end 🙂 ) and I’ve gone bonkers over it. In fact, I’ve wasted far more time than a sane person should playing with it.
I had to bookmark it and I go to it several times daily… yep! I’m addicted.
Make sure your volume isn’t muted, but don’t turn it up too loud if you’re at work (your boss WILL catch you!).
Careful with the “Manic” mode — you won’t be the same afterwards!
Once you see it, and you’ll recognize it instantly. Go ahead… you know you want to!
