wall decor: collages

I love the idea of clusters of photos or other items on a wall. It really draws the eye abnd creates some intrigue. I want to create a wall like this in my living room and cover it floor to ceiling in items. All different shaptes and sizes, and different textures and depths. But I want each item to be meaningful, so I need to start collecting now!
