I belong to the Volusia County Orchid society and we had Martin Motes come to the meeting bringing some beautiful vandas. He gave his lecture on warm growing vandas, the one that he did at the 18th WOC 2005 in Dijon France, and I seem to always learn something new. I brought in Aerv. Kinnarree ‘Redland Gold’ AM/AOS and it had begun to twist. He gave me a small tidbit that I needed to turn the plant so that the axis of the leaves run east to west. I never thought that it would make a difference but according to him, the plant will seek the sun where it gets the most sunlight on it leaves. I went home and went out to the shade room and noticed that he was right. I didn't have many turned the wrong way but the ones that were, were twisting in the basket.
Here is my pic of my Aerv.:

P.S. This orchid is very fragrant....it knocks me over in the morning when I go out to the shade room
