Overview

A six-tab interactive visualization of what lies beneath the Earth's surface, from the thin layer of topsoil just below your feet to the solid iron core at the planet's center. Each tab runs a live animated simulation alongside a detailed explanation panel covering the science, ecology, and practical applications of underground systems.

Content

Soil Layers — A full cross-section of the ground showing the six soil horizons from the dark organic layer at the surface down through topsoil, subsoil, parent material, bedrock, and lower crust. Layer boundaries are animated with gentle wave motion. An animated scan line moves up and down the cross-section and updates a live depth readout. Each layer lists its composition, color, depth range, and key characteristics on the right side of the view. Trees with recursively drawn root systems sit above the surface.

Groundwater — Shows how rainwater infiltrates the ground and accumulates in underground water-bearing layers. Animated particles represent falling rain, downward infiltration, and lateral groundwater flow. The view distinguishes the unsaturated zone above the water table, an unconfined aquifer, an impermeable clay aquitard, and a confined artesian aquifer below. Two wells are illustrated — a standard shallow well drawing from the unconfined aquifer, and an artesian well that flows under its own pressure without pumping.

Earth's Interior — A rotating cross-section of the entire planet showing the six internal layers: crust, upper mantle, transition zone, lower mantle, liquid outer core, and solid inner core. Slow rotation animations illustrate mantle convection and outer core circulation that generates Earth's magnetic field. Labeled leader lines on the right give depth range and temperature for each layer. A fact box notes that the deepest borehole ever drilled reached only 12 km — barely scratching the crust.

Underground Ecology — A living soil cross-section populated with animated earthworms, beetle larvae, ants, moles, and cave beetles moving through their tunnels. Recursive root systems grow downward from three surface trees. A faint mycorrhizal fungal network connects the root nodes across the soil. Depth bands on the left label the ecological zones from the surface litter layer down to cave and aquifer life.

Minerals & Fossils — A dark rock face scanned by an animated ground-penetrating radar beam. Embedded across the rock are glowing gems (ruby, sapphire, emerald, diamond, amethyst), metal nuggets (gold, silver), fossils (ammonite, trilobite, fern imprint, shell fossil), and common minerals (quartz, feldspar) — each labeled with its chemical formula or geological age. Gems rotate slowly and pulse with a colored glow.

Geothermal Energy — Shows Earth's temperature gradient from 25°C near the surface down to 1,200°C at depth, visualized as a color shift from cool brown to deep red. An animated geothermal power plant injects cold water down one well and extracts hot steam from another. Rising heat particles drift upward through the rock layers. A temperature scale on the right marks each depth band. A power line carries the generated electricity toward the grid.

Everyday electrical and electronics knowledge for non-specialists — interactive visualizations covering home electrical safety, series and parallel circuits, fuses and circuit breakers, grounding, battery capacity, LED vs incandescent power comparison, outlet overloading, and the difference between AC and DC.

Parking Lab — Interactive Car Parking Simulator

Parking Lab is an interactive, browser-based parking simulator designed to help users understand vehicle movement, steering behavior, parking alignment, and spatial awareness through direct visual interaction.

Instead of simply explaining parking techniques, the simulator allows users to control a virtual vehicle and practice different parking scenarios in real time. Users can steer, move forward or backward, observe the vehicle's path, monitor surrounding obstacles, and receive immediate feedback on parking accuracy.

Key Features

Perpendicular & Parallel Parking

Practice two common parking scenarios and learn how vehicle position and steering angle affect the final result.

Interactive Vehicle Control

Control the vehicle using steering and speed sliders, on-screen controls, or WASD keyboard input.

Real-Time Steering Simulation

The vehicle responds dynamically to steering angle and forward/reverse movement, providing an intuitive representation of basic vehicle motion.

Vehicle Path Visualization

Display the path traveled by the vehicle to better understand turning trajectories and how steering decisions affect positioning.

Parking Sensor Simulation

Front, rear, left, and right sensors provide approximate distance information to nearby obstacles.

Collision Detection

The simulator detects contact with surrounding parked vehicles or boundaries and immediately displays a collision warning.

Target Parking Bay

A highlighted parking area provides a clear objective for each exercise.

Parking Performance Evaluation

Parking results are evaluated using several factors:

• Position accuracy
• Vehicle alignment
• Obstacle clearance
• Collision status

These measurements are combined into an overall parking score.

Responsive Interface

The simulator supports both desktop and mobile layouts, with keyboard controls for desktop users and dedicated on-screen controls for mobile devices.

How It Works

Select a parking mode, then control the vehicle's steering angle and movement to guide it into the highlighted target bay.

As the vehicle moves, the simulator continuously calculates its position, heading, proximity to obstacles, collision state, and alignment with the parking space. The evaluation panel updates in real time so users can immediately see how each maneuver affects the final parking result.

Parking Lab is designed as an educational and interactive visualization rather than a real-world driving system. Vehicle physics and sensor behavior are simplified to make parking concepts easier to explore and understand.
