Orchids for window growing?

[atmccmn]

David, the first one is an oncidium. Sorry! me also don't what name it was. All I know is oncidium. Mine was mounted as I was advised to plant it with coarse charcoal. It comes in an array of colors like pink, maroon, yellow, red & etc.....
The second one is maxillaria......something. I also have that mounted to driftwood. I put mine at very shaded area so, it looks like a bulb sprouting grass..
