Inspiration

Modern digital tools track where our time goes, but they miss something far more interesting: the moments where attention almost commits but doesn’t.

While observing our own behavior online, we noticed a pattern. We repeatedly hovered over the same ideas, reopened the same messages, revisited the same profiles, researched hobbies we never started, and saved things for “later” that never came. These tiny moments felt random, but they kept returning.

We realized these moments leave behind a signal and that is what we call attention residue.

Attention residue is not where attention goes, but where it almost went. Hovering, revisiting, hesitation, rereading, and unfinished interactions all leave traces of curiosity, avoidance, or cognitive noise.

Yet today there is no interface that allows people to perceive these signals.

What it does

Lint was designed as the first tool that makes this invisible layer of attention visible. Instead of presenting data dashboards, we created a living interface: a small digital creature that quietly collects the fibers of attention users leave behind as they navigate the internet.

As users interact with digital environments, Lint gathers these fibers and gradually reveals patterns. Some signals reflect genuine curiosity, others represent unresolved emotional loops, and some reflect compulsive or low-value attention. By visualizing these patterns, Lint helps users distinguish between the things that genuinely interest them and the noise that fragments their focus.

This introduces a new cognitive sense: the ability to perceive patterns in unfinished attention.

The goal is not productivity optimization. Instead, Lint supports a new form of mental wellness built around attention awareness. When people understand the signals their attention leaves behind, they can more easily identify emerging interests, close unresolved loops, and reduce cognitive clutter.

Over time, users become better at protecting curiosity, resolving emotional hesitation, and reclaiming attention from this busy overstimulating algorithmic noise.

How we built it

Building Lint required balancing speculative sensing with a playful, emotionally engaging interface. We intentionally avoided intrusive notifications or analytics-heavy dashboards. Instead, we designed Lint as a gentle companion that quietly observes attention patterns and surfaces meaningful insights at the right moments.

The biggest design challenge was translating abstract behavioral signals into a visual language that felt intuitive and human. We solved this through thread and fiber metaphors, allowing attention patterns to appear as glowing threads, tangled knots, or drifting fuzz around the creature.

Challenges we ran into

The biggest design challenge was translating abstract behavioral signals into a visual language that felt intuitive and human. Attention residue is invisible and difficult to represent, so we had to design a system that communicates patterns without overwhelming users with data or analytics.

Accomplishments that we're proud of

We created a system that transforms subtle behavioral signals into something people can actually perceive. Instead of charts or productivity metrics, attention patterns appear as threads and fibers that Lint gathers and reflects back to the user. This allowed us to design a new type of interface where behavior patterns feel alive and understandable.

What we learned

Through building Lint, we learned that attention is not just something people spend. It is something that leaves behind traces. When those traces become visible, people gain a new perspective on their own curiosity, hesitation, and digital habits.

What's next for Lint

Lint ultimately proposes a new design direction for digital wellness: tools that help people understand their attention span and residue rather than simply measure it.
