Bromeliads I guess, those airplant you can get from local sites like tillandsia.com.sg
They use some sort of hot glue to attach the baby plants to different surfaces. Problem arises when the part of the plant that is attached to the surface via the glue starts to rot, then the attaching factor is gone. Should be pretty easy for you. Other option is to use those hanging fern and attach them to the artificial background. Still, if you prefer the current look, it works too. Less work to clean..
I figure Wild Ginger, or one of the vivarium folks will have better suggestions.
