Animmerger stitches 2D images together into either a static image or an animation, while attempting to preserve a global frame of reference (static background). That is, for a movie that follows an actor around (and the background scrolls to follow them), it creates a movie that has a fixed background, and the camera moves around in the scene. The most obvious application of animmerger is in automatic map stitching for 2D video games, but there are many general purposes for which the program can be used. Its color quantization and dithering algorithm set is particularly advanced.
Wu is small command-line application that retrieves weather data from Weather Underground (including current conditions, historical data, forecasts, active alerts, and station lookup). The program is designed to be extremely fast and generally compliant with the Unix philosophy. Wu is written in Go, and requires a Go compiler to build from source.
SearchBin is a fast commandline program for searching within binary files. It's a bit like grep for binaries. It offers wildcard matching and has three capabilities for searching: for bytes using hexidecimal, for a plain text string, and for a smaller binary file. Any discovered matches will print the found offsets (0-based).
Tiny Life (tlife) is a simple Game of Life implementation designed to work as a filter for the shell, operating solely through standard input and output, with an emphasis on shell integration rather than pretty visuals. It supports customizable output and board sizes, custom rulesets, and random and user-specified seed values for the starting generation.
