My son and daughter share a room. I don't have pictures, but there are 2 beds--one twin, one toddler--both against walls, kind of in an L shape by the corner of the room. There's a table and chairs in the middle of the room, and 2 dressers and 2 storage systems for toys/art/sports equipment, etc.
Her bedding is pink with Dora (she picked it out) and ds's is a blue comforter. Stuff on their walls is mostly their art, and also a poster from kids science day at the local U. They're now 6.5 (ds) and 3 (dd) and don't seem to mind sharing a room at all, though the plan is to move this year and get a bigger place, because I think ds is getting to an age where he might like some space from his sis.
