HIRUJA STUDIOS / EST. 2020
A one-person creative technology studio exploring software, games, web experiences, experimental computing, mathematics, physics, and everything interesting in between.
SPECIMEN 01 — CONTAINED EXPERIMENT
PHILOSOPHY
SELECTED WORK
A collection of things I’ve built, tested, broken, rebuilt, and occasionally managed to finish.
An astronomy-focused digital platform exploring image processing, sky observation, intelligent planning, satellite tracking, and tools designed to make astronomical observation more accessible.
A cozy-chaotic 2.5D browser platformer created in just 6 hours for the EXE Extended 2026 Game Jam.
Built entirely with HTML, CSS, and JavaScript — without a game engine, WebGL, or AI tools.
Play ClayWay UpYou are the keeper of a fragile community. Build a bridge while mysterious paper boats drift toward you. Every boat carries a wish, reward, or curse — and every decision affects the survival of your people.
A full-suite web application for students combining organization tools, shared notes, an AI assistant, and study planning into one platform.
A CSS toolkit built around the idea of making expressive interfaces faster to create using custom HTML elements instead of class-heavy styling.
Older releases remain available as an archive, but the project is no longer maintained.
View ArchiveA free, ad-free chess training tool designed around calculation. Instead of solving preset puzzles, players calculate positions taken from real games.
The project is currently unavailable due to hosting costs and insufficient usage to sustain the server.

ABOUT
Hiruja Edurapola is the founder and sole creator behind Hiruja Studios.
What started in 2020 as a collection of small web games and experiments gradually became an umbrella for software, games, research-oriented projects, creative technology, and things that were simply too interesting not to build.
Skyora, ClayWay Up, and new experiments.
No departments.
No committee meetings.
Just one person asking, “What if?”
PRINCIPLES
Questions are often more valuable than answers.
Build it. Break it. Understand why.
Technology becomes more meaningful when more people can explore it.
Code is a tool for expression, not just computation.

FROM THE NOTEBOOK
Notes from building ClayWay Up for a game jam without touching a game engine — what breaks first, and what you learn about physics by faking it badly.
Image processing pipelines, catalogue data, and the surprising amount of math required before a single star renders correctly.
An experiment in replacing class-heavy styling with custom elements — and the tradeoffs that eventually shelved it.
A running list of the dumbest bugs, the smartest accidents, and why leaving something offline is not the same as abandoning it.

I’m always interested in strange questions, ambitious experiments, and things that probably shouldn’t work — until they do.
