A SMALL CORNER OF THE INTERNET, FOR CURIOSITY
A growing collection of tools, experiments, and little websites that make you want to click around. Pick something. See where it takes you.
THE COLLECTION
Build a complete song. Draw notes in a piano roll, layer eight instruments, arrange clips, shape sounds and automation, import MIDI, and save projects in your personal library.
Build Arduino circuits with manual right-angle wires, preset colors, component rotation and copy/paste, native C++, instruments and pinned libraries.
Find your next color crush. Generate palettes, extract colors from an image, and preview combinations. Save favorites and export CSS or PNG.
A little help for everyday things. Named timers, focus cycles, stopwatch, unit conversions, percentages, dates, bill splitting, recipe scaling and a time-zone planner.
Curve a ball. Tumble a tractor. Explore 3D flight, bouncing, gusts, force graphs, target challenges, automatic experiments, and saved discoveries.
Explore density, displacement and floating steel hulls. Try a cargo challenge with metric or US/imperial mass, volume and force measurements.
One lab for Flow, 3D and Waves. Stir dye and smoke, shape currents around objects, build wave experiments with sources and barriers, and save or share your discoveries.
Find a little infinity. Save favorite discoveries, record zoom videos, link Mandelbrot and Julia views, and export HD or 4K wallpapers.
Your own little universe. Launch planets, build orbits, change gravity, and watch worlds collide. Save your creations and come back later.
Four experiments, one Heat Lab. Cool drinks, follow temperature clues, design winter gloves and explore coastal climates—with metric or US/imperial measurements.
Follow a little light. Arrange mirrors, lenses, prisms and glass; explore reflection, rainbows, and real or virtual images.
Explore dated planetary and moon positions. Change your perspective, drag a planet through time, and compare worlds.
Find your pattern. Make kaleidoscopes, draw reflected lines, trace spirographs, and create geometric art. Export your creations as PNG or SVG.
Ten ways to give your mind room to play. Explore 1,000 ladder puzzles, practice techniques, and optionally sync progress and bookmarks across devices.
Choose a mountain. Explore its trails, ride lifts, and try skiing or snowboarding in 3D. Start with Okemo, Vermont—more resorts are coming.
Follow the Milky Way, find galaxies and nebulae, and zoom into dated Moon and planet views. Explore your sky and share what you find.
Build a wave. Mix a signal. See—and hear—how simple pieces become something extraordinary.
Design a shape. Send it into the wind. Explore airflow, pressure, and swirling wakes in an interactive 2D wind tunnel.
No matches yet. Try “sudoku”, “fluid”, “space”, “wave”, or clear your search.
