A Helsinki skatepark captured as an interactive Gaussian splat

Suvilahti DIY · Project ETERNAL

A drone-aided Gaussian splat of legendary Suvilahti DIY in Helsinki. The 3DGS model placed third in Project ETERNAL, a global 3D Gaussian splatting challenge by Antigravity, Insta360, and Splatica.

01 Problem

Problem

A small group of local skaters started building Suvilahti DIY in 2011, creating it through volunteer work into a concrete park known far beyond Helsinki, visited by international skate legends like Tony Hawk. Demolition work is scheduled to begin in October 2026 as construction moves into the surrounding Suvilahti area.

02 Approach

Approach

We flew around, on and above the skatepark with a 360-drone, then processed the footage locally on an M4 MacBook Air with open-source Gaussian splat training tools. The slightly cleaned up result is a lightweight browser-based 3D scene that can be explored on its own.

03 Outcome

Outcome

  • The park can be explored as a spatial scene.
  • The scan preserves the park’s geometry and surface detail as captured in June 2026.
  • The project placed third in Project ETERNAL. A portion of the prize money was donated to another Helsinki-based skate DIY initiative.
  • See the Project ETERNAL challenge.

Worth knowing before you write a brief

AppsFlyer's 2025 benchmark across 28 billion installs puts Day-1 retention at around 25%. AR apps sit below that floor, because every reviewer is a single-use case, not a habit. WebAR removes the funnel. The link that opened the experience the first time still opens it the second.
