A few blocks south of the National Mall and the Smithsonian Metro Stop, the place is mostly underground. They recommended an app for an interactive experience, but the app would not work on my Google pixel. The tour was a brief introduction and then we were free to wander the exhibits as we liked. Made by an Italian group, it was overall pretty interesting. There's a main room with about a 10-15 minute cycle of partical animation. The room on the right didn't show much. The room on the left was interactive with particulates interacting with your presence before a screen. The back room showed live Tweets and judged their emotional quality. I didn't like the merciless flashing, but the live data analysis was rather cool. ArTecHouse was a good experience, but it seemed rather small overall. At the request of the venue, they asked photos taken only be for personal use, so I'm not posting any of the actual exhibits.
