The photos make this plant look a lot larger than it actually was. I was actually surprised by the size.
Last year's show had a Phalaenopsis Kaoda Twinkle as well, with no varietal name; this is probably not the same specimen as that one, but I wouldn't rule it out.
Don't really have much to add to this; in February I said it was one of the few Phalaenopsis I would actually want to have personally, and that remains the case. My track record with orchids is bad enough that I'm not actually trying to locate one (I'm actually pretty desperate to get rid of plants right now: I need more space for Anthurium and Schlumbergera seedlings and have nowhere to put them.), but I'd have a tough time turning one down if I saw a reasonably-priced one in a store.
Phalaenopsis Kaoda Twinkle 'Dusty's Midnight' = Phalaenopsis schilleriana x Phalaenopsis Malvarosa Valentine Pearl (Ref.)
