Do you rotate your orchids to change direction of sunlight?

[cythaenopsis]

When growing a plant with sunlight coming from a single direction, I periodically rotate the plant so that it gets more uniform sunlight exposure. It also helps to keep the leaves growing evenly.

With orchids, I'm wondering if this practice has any merit. Certainly on Phals, it doesn't look like the leaves pivot to get optimal sunlight exposure. Still, is it a good idea to rotate them?

Also, there are other species of orchids with smallish leaves that seem to be more sensitive to sunlight direction. I've got one in particular, an Encyclia Dickensoniana, where the leaves do appear to twist in reaction to the direction of sunlight. I try to give even sunlight exposure for it. I guess ideally it would be great to have a set of corner windows for multiple angles of sunlight.
