#38: really like the idea of the house with the arrow which looks like a smiley. not sure about the font - looks too heavy.
#36: on its own the house/smiley is a nice facebook app icon. plus point for sure.
#35: same as
#38. really like it. can you do something subtle to "mooove" and "on" show up as distinct words,
#34: like this a lot. very simple and pleasing.
