"Display center" is the center of the screen.

World and Display often have the same bountries.

myMorph postition: Display center . 
Will put the morph top right at the center. Therefore the center of the morph will be more towards the bottom right.

myMorph center: Display center .
Will align the two centers which is usually what's wanted.

myMorph openCenteredInWorld .
Will usually put a newly created morph in the center. It can do other things depending on how myMorph deals with layout when sent the selector #openCenteredInWorld.
