i need ideas

i got the above items while in DesMoines, at an architectural salvage business....they are 3 old door locks and one old kitchen drawer handle....any ideas on what i could do with them in a mixed media application?? i have a few ideas and can't wait to try them out....

this place was fabulous...there were 4 or 5 floors of everything imaginable! it was a virtual "feast" for my eyes!!! the business was housed in an old factory type building , with a very hip and cool coffee shop on the street level.......

i would love anybody's ideas!!!
