What else can i use besides a memo board to actually place a lot of pics on my wall?

I have seen lots a girls have these memo boards on there walls with a lot of pictures and well i am wondering where i could possibly get one and if there are other ways besides using a memo board to actually hang a lot of pics up without frames as well, its specifically for my dorm room.|||ok so theres this thingy..im not sure what its called, but its basically a long or short, string, with a bunch of clothespins. so basically u pin up the two ends of the string to your wall and then u clip your pictures to the clothespins and yeah. you could probably make one to customize it, you could use a ribbon, and on the clothespins, you could glue giant letters on them so they spell soemthing out...idk just saying ...i think its a pretty good idea, and its easy to like take apart and stuff
