Bizarre is a good for for it as well. I think your theory is a good and plausible one though most of the pics I saw when I Googled high convective clouds looked to be attached to a thunderhead or large cloud mass of some type and I don't think these ones were. I typed swiss cheese clouds into Google and then found ones called cirrocumulusclouds that look kind of similar. I'm not sure if they're the same or not either, they still kinda look a lil different. Anyways... Thanks for the feedback, glad you appreciated the image!
