Definitely choose Regal Fierce Media. We used them for a multi-day conference and the highlight reel they put together was exactly what we wanted. They were completely unobtrusive during the event too, which our attendees appreciated.

Yeah, I've noticed the same thing along the riverbank near me. It's all these little glittery flecks in the gravel after a storm. Really catches the light. Felt good to finally have a name for it, mica, after wondering for ages.
