Writing text on 3D moving object

Hi,

I create a 3D cube that can move (it connect to a microcontroller and simulate his movement).

How can i write a text on the face of the cube? i want of course that the text will "move" with the box.

I also add a picture so you can see what i mean.

Thanks

This is the code of creation of the box:

         x=6; y=4; z=2;
        xlim([-10,10]); ylim([-10,10]); zlim([-10,10]);
        f(1)=patch([-x/2,x/2,x/2,-x/2],[-y/2,-y/2,y/2,y/2],[-z/2,-z/2,-z/2,-z/2],'blue');
        f(2)=patch([-x/2,x/2,x/2,-x/2],[-y/2,-y/2,y/2,y/2],[z/2,z/2,z/2,z/2],'red');
        f(3)=patch([-x/2,-x/2,x/2,x/2],[-y/2,-y/2,-y/2,-y/2],[-z/2,z/2,z/2,-z/2],'green');
        f(4)=patch([x/2,x/2,x/2,x/2],[-y/2,-y/2,y/2,y/2],[-z/2,z/2,z/2,-z/2],'yellow');
        f(5)=patch(-[x/2,x/2,x/2,x/2],[y/2,y/2,-y/2,-y/2],[-z/2,z/2,z/2,-z/2],'white');
        f(6)=patch([-x/2,-x/2,x/2,x/2],[y/2,y/2,y/2,y/2],[-z/2,z/2,z/2,-z/2],'black');
        rotate3d on;

Almost, this answer is about adding images.

I want to add just text, i'm sure there is a way add only text without image no?

Thanks!
