Some of those look really cool. I only own 3 orchids right now so I just don't know what to get next.
Do you know of any tiny orchids that have bundles of small leaves that require constant moisture and decent light? I've got a lot of orchid studying to do

. I saw a pic of something like that a while back somewhere and I think the guy had it very near a waterfall. It seemed to make more of a ground cover appearance than bulbs....
I would like to put something miniature like that on the side of the waterfall. But I'm having a hard time finding a place to start.....looking into miniatures now.
