# sissi

> sissi (pronounced "see-see"; also CC, 西瓜, 汪熙宸 / Wang Xichen, 茜茜) grew up in an urban village in Shenzhen and now lives in San Francisco. Has a lot of hearts: "home is where your heart is." Likes Moomins and Minions and resembles their traits. Builds beautiful things, hitchhikes (footnote: a photo of steel house numbers 42 on an amsterdam door, as in the hitchhiker's guide to the galaxy; photo by andré van b, cc by-sa 2.0, via wikimedia commons), yaps, writes sometimes, consumes a lot: books, videos, websites, papers, music (currently How to Travel with a Salmon by Umberto Eco), swims semi-professionally, has a lot of fun, and collects wonderful humans.

Ask her about: "the world is a paidia" (paidia.html), Richard Feynman, DishBrain, and next-gen actuators for humanoid robots (https://actuators.trymaglev.com).
