@Hernan Sending a message to an object using the inspector allows me to do: self addMoprh: EllipseMorph new.
But what I want is to add a morph to another morph that is already instantiated. I want to reference the object that is somewhere in the memory an be able to manipulated even if I have not assigned it a reference | aMorph |. @Sean As I told you, your Self World is impressive. I see how easy is to do what I want in that Self World. I will take a look at MathMorphs, I think I've tried to make it work in Pharo but had no success.
