There's a fairly good chance the plant is Zygopetalum Blue Blazes, although there are several quite similar ones. The shape, color & patterning of the lip are all really good matches, as are the tepals. Unfortunately, there seem to be very few photos of these on the web. OrchidWiz shows a few--if it were possible for me to e-mail you one of the photos from it, I'd be happy to do so, but I don't believe the program has that option. Others that look close are Zygo Redvale, Zygo Blue Banks & Zygo New Era. Again, though, the few photos on the web didn't look nearly as close to your photos as the OrchidWiz photos.
