Coffee Rings Cartography

This app is for experimental physicists, artists of random processes, and collectors of ephemeral phenomena, dedicated to documenting and analyzing the patterns left behind by the evaporation of coffee droplets. It transforms a random spot into a fully-fledged specimen with a history: you capture not only the image of the ring but also its origin, context, and environmental parameters, allowing you to later revisit your observations, compare them, and build your own collection of capillary maps. The work begins with laboratory input: you create a new record, specify a sample ID, and indicate the liquid source, such as espresso, cold brew, or instant coffee. Then, you select the surface on which the trace formed, be it glossy paper, a napkin, or another substrate, and add observer notes. These notes are a convenient way to record any details that don't fit into formal fields: how the drop was spilled, how fresh the drink was, the surface texture, how the result felt, and why you think this particular pattern is successful. The app then offers an analysis stage, where the visual form is translated into measurable characteristics. A geometric profile is constructed for the ring: the diameter, rim thickness, degree of symmetry and regularity, and particle density within the deposit are assessed. These parameters help describe the pattern not only verbally but also numerically, identify similarities between different samples, and notice patterns that are difficult to discern by eye. To ensure that each trace remains linked to the conditions of its formation, environmental data is stored in the record. You attach an image of the sample and record atmospheric parameters such as temperature and humidity, as well as the temporal stability of the pattern, for example, whether it remains stable or noticeably degrades over time. The result is a neat record that combines aesthetics, physics, and context: the image, conditions, notes, and the analytical profile. The collected samples are stored in a digital Atlas, where they can be easily searched and reviewed by identifier, liquid source, or surface type. The collection doesn't become a chaotic gallery: it's an archive of observations that can be expanded, filtered, and used as a personal file cabinet. For those who enjoy comparing results, a comparison mode is available: select two samples and see how their key indicators and pattern characteristics differ, as if comparing two prints of the same phenomenon under different circumstances. A separate analytics section provides a comprehensive picture of the entire collection: how many samples have already been saved, the average aesthetic rating, which sources are most common, and how observations are categorized. Thus, the app functions simultaneously as an experimental diary and an art catalog, where each coffee circle becomes not a trace of trash but a hydrodynamic signature, carefully described, measured, and meticulously preserved.
