I have no idea (40/365)

I have no idea how I got this picture here?
It is a picture of a corner of my desk. The picture involved my android phone; Google+ (whatever that is); and my p.c. in which I use Linux Ubuntu 12.04. I'm glad I was able to do it but confused about what I did or how I did it?
Not so much an exercise in photo-graphics, but rather a stumble through - trying to understand some ever changing software.
Anyway, it's number 40 of 365 - so I'm "getting there"?
