[Pharo-users] rotating a morph through messaging

I am experimenting with pharo right now, particularly with Morphs. The weird thing is that some morphs can have a rotation halo and others do not. This has a "rotate halo": bar := EllipseMorph new. bar openInWorld. This does not: foo := Morph new. foo openInWorld Am I missing something? Also, how do I send message "rotate" to a morph? I can't seem to find a "rotate" method anywhere in the browser. - Steve
