Is it possible to acquire a custom Arduino

I was wondering if I could get a Arduino screen that was in three pieces which were more complex than that of the baisic Arduino. If possible please tell what is the smallest that it can be made.

Anything can be customized. What would the 3 pieces be?

Do you mean a display when you say screen? Yes you can have three displays, but the available memory on a Uno will rule out using a graphics library with them although you can still use a text only display.
