A system to provide scents includes a scent receiver to replaceable receive scent carriers that carry scent media, a scent actuator operable to controllable release scent, and a configurable circulation subsystem. Peltier devices may used to induce active heating and active cooling of scent media according to defined scent sequence information or scent tracks. The system is also operable to collect air, including scents, from an ambient environment, and temporarily retaining such for sampling by a user. Scent tracks may be defined and shared amongst users and other entities.
