It guesses the person you're thinking of

Combine the four elements into an entire world

Turns useless curiosity into a pile of little toys

Someone in a photo always points at your cursor

Every click throws you at another useless website

Pour colored sand on your screen

A parallel universe with an operating system that never existed

Physics and engineering explained through playable diagrams

Machine learning papers, visualized

One interactive idea per page

Explanations you can play

Statistics and algorithms explained with visuals

A color palette in three seconds

A hand-drawn style whiteboard

An open-source API console

A full Photoshop running in your browser

Squeeze images down to almost nothing

A computational knowledge engine that actually calculates

Every music genre in the world drawn as a galaxy map

Background sound for writing code

Every key is a drum hit

Spin the globe and tune into radio stations worldwide

Typing turns into a melody

A painting you can zoom into forever

Marginal notes on classic papers

Science and humanities essays

The numbers behind our world

The numbers behind culture, told with visuals

Big questions written up as very long illustrated posts

Guess the place from street view

A library holding every sentence you could write

Drops you onto a random street in the world

Step inside video game maps

A real Linux running in your browser

The internet archive

Look out of someone else's window
