1. African nesting elephants

2. Binary planet. It's either there or it isn't.  

3. Telepathic lumber. It literally tells you how to put it together.

4. Invisible butterflies. How do you know they aren't actually there? Hm?

5. Remote control leaves.

6. Auto biography of a desk lamp. Granted it was a very famous and popular desk lamp.

7. Fireflies in spacesuits.(Because +Bliss Morgan  did a thing and +richard brooks  commented on it)
