Penumbra: Technical Solutions

Case study

For our project with Penumbra, we had full creative and technical flexibility, which meant we could choose the best tools to deliver both performance and visual depth.

- WebGL shaders power the hero animation with smooth, high-performance visuals.
- Rive animations add lightweight, non-linear interactivity to the interface.
- Lottie handles elegant, looped microinteractions — a perfect match for subtle motion design.
- And when nothing on CodePen matched our vision, our digital art director Kostya Ostro built the custom glitch effect from scratch, with a little help from ChatGPT.
