Orchid in flower

We enjoyed a public holiday here in Brisbane yesterday, for our show day otherwise know as the 'Ekka' it finishes this weekend. I spent pretty much most the day in the studio working on my pieces for our up-coming exhibition - "Undercurrents". While enjoying a cuppa break, I noticed that one of our orchids is flowering. We've been in our humble home for about five years now and it's the first time we've seen this orchid flower. At some stage I'll work out which variety of orchid it is, it will be good to have the photos as a reference.
