The user experience begins with selecting a starting point on the interactive map. This point represents the hypothetical location where the simulated raindrop lands. Once initiated, the simulation dynamically renders a blue line, representing the raindrop's projected course, as it descends from its origin, navigating the complexities of the landscape. The path delineates the expected flow of water, aggregating into rivulets, streams, and eventually rivers, faithfully adhering to the valleys and depressions of the terrain. As the simulated raindrop progresses on its journey, the application dynamically highlights the accumulating watershed area, visually demonstrating the extent of land contributing to the flow. This highlighted area, depicted in a progressively intensifying shade of blue, illustrates the interconnectedness of the hydrological system and the cumulative effect of individual raindrops on larger bodies of water. The simulation continues to trace the raindrop's path until it ultimately reaches its final destination, typically an ocean or a major inland body of water. In this way, "River Runner Global" provides a compelling and educational visualization of the Earth's drainage networks, showcasing the intricate pathways by which water moves across the planet's surface and ultimately converges into larger water systems. This tool offers a unique perspective on the interconnectedness of landscapes and the dynamic processes shaping our world's hydrology.

  Mercator: Extreme pushes the boundaries of the web Mercator projection by visualizing the entire world map at incredibly high zoom levels, far beyond traditional map applications. It demonstrates the inherent distortion of Mercator as landmasses become increasingly stretched and warped, especially near the poles. The project uses custom tiling and rendering techniques to handle the immense detail required for such extreme zoom levels and allows users to interactively explore this unusual cartographic perspective.

  The blog post entitled "Mercator: Extreme" by MrGris details an extended exploration and visualization of the Mercator projection, a cylindrical map projection method renowned for preserving angles and shapes, making it particularly suitable for navigation. The author meticulously demonstrates the inherent distortion of area that increases drastically with latitude as a consequence of this projection. While conventional Mercator maps typically truncate at latitudes around 85° North and South to mitigate the visual exaggeration of polar regions, MrGris pushes the boundaries of this representation by computationally extending the projection far beyond these conventional limits.

  The post presents a series of images showcasing the ever-increasing distortion, depicting Greenland ballooning to improbable sizes, ultimately exceeding the apparent size of Jupiter in the projection. This visually striking exaggeration serves to highlight the mathematical nature of the projection and the exponential growth in apparent area as one approaches the poles. The author explicitly notes the theoretical limit of the Mercator projection existing at infinity, as complete representation of the poles is mathematically impossible within this projection system. The visualizations are accompanied by brief explanations of the underlying principles that cause this distortion, emphasizing the trade-off between preserving shapes and accurately representing areas. The project serves as a thought-provoking demonstration of the limitations inherent in any two-dimensional representation of a three-dimensional sphere and the specific distortions characteristic of the Mercator projection. The extreme visualizations, culminating in Greenland dwarfing Jupiter, offer a compelling and memorable illustration of the mathematical realities of mapping the Earth.
