Is Picture Arranging A Hobby?

I printed some pictures that I have taken over the past few weeks on my digital camera yesterday. I mostly just upload my pictures to the computer from my digital camera. So I bought a bunch of frames and decided to put all of my pictures up on the front room wall. While I was putting the pictures in the frames, windexing the glass, and measuring the wall for all my frames, I realized that I really enjoy arranging frames on the wall. I liked it better than taking the pictures or printing them. I'm not sure if Picture Arranging is an official hobby but for me it is!
Here is a picture of the frames I did last night! :)
The picture in the upper right hand corner is actually not a picture of us. I haven't had a 5x7 made yet! I will though!
