Mixbox is a specialized simulation engine for modeling fluid color dynamics, pigment-based hue shifts, and latent space color blending. It functions as an RGB color mixing simulator that uses pigment-based simulations and latent space interpolation to produce realistic results. The project incorporates a Kubelka Munk color engine to achieve physically accurate hue shifts and saturated gradients. It also utilizes a latent space color blender to transform colors into latent representations for precise linear interpolation and multi-color mixing. The system covers fluid dynamics for calculating

heatmap.js is a JavaScript data visualization library used to render data density visualizations on a web page. It functions as an HTML5 canvas heatmap library that represents the intensity of data points across a coordinate system using color gradients. The library provides tools for geospatial distribution mapping and user behavior analysis, such as mapping click patterns and interaction hotspots. It is also used to add visual intensity layers to interactive data dashboards to identify trends and anomalies.

Rnote is a vector-based note-taking and drawing application designed for capturing handwritten input. It functions as a digital workspace that records stylus pressure and movement to create sketches and notes, storing them as mathematical paths rather than pixels to allow for infinite scaling and non-destructive editing. The application provides a flexible canvas environment that supports infinite scrolling and various page layouts. Users can organize their work using a layer-based system, which allows for the independent manipulation and ordering of individual strokes, shapes, and background

Weylus is a tablet-to-PC screen mirroring tool and remote input controller that transforms a mobile device into a digital graphic tablet emulator.
