Arduino with 100+ GPIO?

Is it possible to make an arduino with 100+ GPIO pins?

Google centipede shield, IIRC you can have more than one

I was just curious as to what is the need of a 100 Pins of GPIO.

suppose you want to make a piano, or a complex (toy) train control system, or ...

thanks
What I kinda wanna do is control a bunch of servos and lights and buttons, thanks

To control servo's you need a port expander that can do PWM on it's own, otherwise it won't work. Something like this.
