Also when he visites luke on dagobah, branches move when he walks against them, pretty unusual voor a non-material apperance :)

That could be explained by the fact that due to the 'unusually strong' presence of the Force (Yoda, Luke and Obi's spirit), Obi-Wan is able to manifest himself in a stronger form...? (A far-fetched idea, I know!!)
