in reply to multiple textures on a cube (opengl example)

Firstly, I think is is a cool use of OpenGL and I agree that

your child or grandchild may enjoy seeing his/her picture on a face of a rotating cube while his/her pets pictures on other sides of the cube
However, whether they would enjoy seeing this:
glBegin (GL_QUADS); all sex faces definitions here..... glEnd();
Although I guess they have to learn at some time!? ;P

Just a something something...
