Xu Cong. Creative coder — software, installations, and small tools. Based in Chiba, Japan.

This site started as a portfolio. Most of what I build — products, systems, experiments — are not just projects, but ways to explore and express ideas.

I'm interested in technologies not only in how they work, but why they exist, what shaped them, and how they are actually used. Through building, I try to understand how people think about the world.

What I make are often experiments — attempts to test an idea and push it toward something useful. I'm less interested in execution alone, and more in deciding what is worth building in the first place.

This site is a trace of that process.
