This olfactory project by Amy Radcliffe is currently at the top of my inspiration charts.
"The Madeleine is, to all intents and purposes, an analogue odour camera. Based on current perfumery technology, Headspace Capture, The Madeleine works in much the same way as a 35mm camera. Just as the camera records the light information of a visual in order to create a replica The Madeleine records the molecular information of a smell."
Would love to have one of these handy for my Sniffing Booth project.
