I have a clay orchid jug that I keep filled with water. Right now, it just has moss covering it. I used to have masdevallia's tied to it, also pleurothallis. All gone, but the moss is so extensive, that I'll try something again. Lepanthes would probably be too difficult...but its the right size.
The next step is to get some micro-miniature Sinningias (Sinningia pusila...regluar pink and alba) and plant a few in strategic places on the rock. They are like teeny, tiny, micro-miniature Gloxinias. They grow from a very tiny tuber, not any larger than this letter "O". In fact, those big honkin' Florist Gloxinias are actually Sinningias! The micro-miniature ones are so tiny, they'd be comforatable if planted in the metal end of a pencil that has lost its eraser! They grow a rosette of beautiful leaves, like an African Violet and produce beautiful little pink and white flowers on delicate, thin stems. They also bloom easily and often. They are a perfect little plant that is in proportion for use on this "landscape". They'll help to create the illusion of wildflowers growing in the "grass". After I find some of these plants and get them planted, I'll post update photos; but, it will be down the road.
