We used a company called Scent Events www.scentevents.com which actually specializes in creating aromas for wedding and other events, not museum exhibits. They created two scents for an interactive experience where small machine with a fan is triggered to turn on when guests walk by and release the scent into the space. Lest you think that they only do flowers and pretty things, one of the scents they created was for a sewer tunnel--not enticing, but pretty realistic.
