Three vacant storefronts and a courtyard in the East Village are turned into a blood donor center and a gallery—a public place to care for blood health and commemorate the history of blood and activism in fighting against blood-related diseases. Flexible by design, gallery rooms can become donor booths, and benches double as donor chairs. Extended storefronts become extended public space. Open all year round, respond to any call: call for blood, call for activisits.
