Explore the
digital frontier
Interesting technology, everyday online safety, and the ideas hiding inside familiar things.
A little curiosity goes a long way
This rocket is made of circles.
Nothing here knows what a rocket is. A handful of rotating arrows simply happen to agree on where the pencil should go.

An encrypted connection is valuable. Deciding whether to trust the destination takes a different kind of attention.
Why the shortest route can make you late
A tiny road network reveals the question hiding inside every “best route.”

Visual stories that make the digital world a little less mysterious.
The curve hiding inside a font
Four points can describe a flowing line, even when the line never passes through two of them.
An island made without drawing a coastline
A few scales of variation and a sea-level threshold can turn numbers into a place-like shape.

A maze is a graph wearing walls
Remove the decoration and a good maze becomes a surprisingly tidy question about connections.
