The need

The dominant story of technology asks the rest of the world to modernize by importing Western tools — and Western values — at the cost of their own. Anastasha asked a different question: what would technology look like if it grew from a tropical, Southeast Asian worldview rather than being translated into one?

The approach

Tropical Technologies is a body of work rooted in cultural value systems instead of borrowed defaults: tangible form over screens, ritual and magic over pure utility, and the slowness of “island time” over relentless speed. The method was as much making as research — speculative artifacts, participatory experiences, and a makeathon to bring others into the inquiry.

The artifact

Lagu Hantu is its flagship — a sound installation of sensor-embedded hardwood panels tuned to the Indonesian pelog scale, shown publicly at Dolores Park in San Francisco and at the d.school. Alongside it: a rain-sensing Balinese gong and a “Silly Bots” makeathon that invited others to build playful, culturally rooted machines.

Why it matters

Lagu Hantu is a proof that advancing and remembering aren’t opposites — that a community can build the future without erasing where it came from.

“It brings me hope to know that we can advance without sacrificing where we came from.”
