Recomendations for easy to grow lithophytic orchids

[Amanvari]

I have several Balinese stone statues in my Garden. They look great covered in moss and I was wondering which orchids could be easily grown on them. The climate is subtropical with major rains in Summer decreasing in the Winter. I live in an indigenous coastal forest which means that most of the garden is in partial shade. Note that humidity is high (esp. in Summer)

I would also appreciate any tips as how to establish the plants onto the statues.
