Mosaic Self Portrait

I'm not 100% sure what I would like to do for this project and knowing my process I'm sure the idea will change throughout time. Last semester I did a mosaic style photo project using a digital camera and my roommate as my subject. It was very successful in the arrangement of the images lining up fairly perfectly but I felt it lacked character in its alignment. I would maybe like to photograph my bedroom or a place where I spend a majority of my time. I feel these areas show a lot of who I am and how I spend my time. I also like the idea of it being in black and white, and would like to bring light in as a main theme in these pictures.
