uncluttered bulletin board

[hugsforcoffee.livejournal.com]

i work at a vet clinic. we like to put up pictures of our clients (animals) in the reception area. for the past billions of years all photos have been stapled onto dollar store cork board. however, i do not like this. i think it is way too cluttered, haphazard and without method. stuff that i dont need in life. the only 'sophisticated' idea so far is that the staff animals pictures will all be in a giant picture frame. (around 20 pictures as opposed to 200 client pics)
pretty much i dont want to staple pictures a zillion times. i dont want messy. most importantly something organized.
so far the only suggestions were to group each species together in different areas of the wall. or to put the pictures together in the shape of an animal.

ANY suggestions please!?!?
