Zoom with a Mandelbrot set explorer
dawn-eagle-forge-eagle.grok.meKorean-language fractal viewer that renders the Mandelbrot set in glowing ink on black. Click to zoom in, drag to pan and scroll to change scale, or jump to presets such as seahorse valley, elephant valley, a triple spiral and a mini set. A slider sets the iteration count, and auto mode keeps zooming on its own. Built with Grok.

Step through the sieve of Eratosthenes
drift-brave-clear-harbor.grok.meA Korean prime number finder that walks through the classic sieve one step at a time. It lays out the numbers from 1 up to a limit you set with a slider, then crosses out the multiples of each new prime so only primes remain. You can play it at slow, normal or fast speed or step back and forth, and tapping any number shows its factors or why it is prime.

Calculate on a virtual slide rule
rd-1-rational-slide-rule.grok.meVirtual pocket slide rule with a geometry face and an algebra face, worked by dragging the slide and a red hairline across the scales. A reading panel lists the value under the hairline on every scale, and presets show multiplication, division, cubes and quadrance. The builder says it follows Wildberger's rational trigonometry, using quadrance and spread instead of square roots, and plate artwork exports as SVG or DXF. Built with Grok.

GrokAbout the app
Interactive probability simulator for learning how chance behaves over many trials. Pick a coin, one die or two dice, set the heads weight, add trials and watch the observed share of each outcome sit beside the expected model in a live chart. It shows the law of large numbers in action: short runs wander, long runs settle near the theory. Built with Grok.

Graph functions and practice transformations
hazel-summit-berry-lark.grok.meArabic-language function grapher that plots one or more functions on a grid with zoom, pan and a live readout of the value under the cursor. It includes 29 guided lessons on translations, reflections, rotations, dilations and basic functions such as sine, parabola, absolute value and logarithm, each with an exercise checked on the graph. Equations can use Arabic or English function names. Built with Grok and shared on grok.me by its creator.

Zoom into a human cell in 3D, scale by scale
beacon-shale-quiet-crisp.grok.meA 3D zoom through a human cell, from the whole cell at twenty-five micrometers down to structures 0.34 nanometers apart. Seven scale steps sit on a ruler at the side, and each stop has a short plain-language explanation and labels such as plasma membrane and nucleus. Scroll or use the arrows to go deeper, and pause or reset the view at any time. A calm way to get a feel for how small the parts of a cell really are.

Spin through an interactive solar system
brush-oasis-spruce-glow.grok.meSolar system orrery that sets the Sun and all eight planets turning on their orbits, drawn for clarity rather than to scale. Tap a world to focus on it, drag to orbit the view, scroll to zoom, change the speed of time with a slider, and press Space to pause. A readout shows how fast a simulated Earth year passes. Built with Grok.
