displaying object''s name in GUIText on mouse over

I need a text with object's name appearing on the screen if the mouse goes over an object...

(I know this shouldn't be too difficult....but I'm new to unity and to scripting and I can't do it)

Put this on the object (which needs a collider for this to work) and drag a GUIText object onto the slot in the inspector:

var textObject : GUIText;

function OnMouseOver () {
   textObject.text = gameObject.name;
}
