If you missed part 1, and/or have no idea what Headspace is, see here. Part 2 is about 75 minutes long, and there's a brief synopsis below the jump.
This video starts out with the second in the series of "accidental perfumers", architect Toshiko Mori, who was paired with perfumers Yves Cassar and Loc Dong. Again we start with a film about the project, then there is a conversation (starting at the 15 minute mark) between Mori, Cassar and Chandler Burr.
Next up are three presentations: first (starting at the 25 minute mark) architect Anna Barbara, then (starting at the 35 minute mark) odor artist Sissel Tolaas, then Toshiko Mori again (starting at the 50 minute mark).
Finally (starting at the 58 minute mark) a panel with Barbara, Tolaas and Mori, moderated by Paola Antonelli.
