A Lobby That Greets You: Guestbook and Ambient Projection at Jungnang Bangjeonghwan
The Jungnang Bangjeonghwan Education Center is a public learning space in Seoul named for Bang Jeong-hwan, the early-20th-century children's writer. The center opened its lobby gallery in 2026 and asked us to make the entrance feel like the kind of place children would want to keep coming back to.
The lobby had two roles. It greeted visitors. It also set the tone for the rest of the center.
What we built
Two pieces of hardware working together in the same lobby.
A single MP-C transparent guestbook canvas, placed near the entrance, where visitors signed in and left short messages. An interactive floor projection, on the opposite side, where the floor responded to footsteps and gathered around children who stood still.
Both ran continuously through the day. Both were operable without staff. Both were sized for short visits — a minute on the guestbook, a few minutes on the floor.
Why a paired install
A single welcome moment is easy to design but hard to make memorable. Two paired moments give visitors something to do on the way in and something to do on the way through. For an education center that wants to feel inviting on the first visit and lived-in by the tenth, that pairing matters.
The guestbook records the visit. The floor makes the visit feel earned.
What visitors experienced
Children read the floor first. They walked the projection like a puddle and figured out the rules within seconds. Parents tended to read the guestbook first, sign, and then catch up with their children. Several families came back the following week, and several signed the guestbook again.
The two scenes are part of the Paintpam library and run with no internet connection. The center's staff swap or update scenes from a touch panel.
Who this is for
Children's centers, education spaces, public libraries, and any lobby that wants to greet the visitor before any signage does. The MP-C panel and floor projection install side by side; they share power and a control layer.
If your lobby is the first impression, two paired pieces will land it better than one centerpiece.
