Four Unique Software Programs: Calligraphy, Halftone, Contour, and ReSolve

Calligraphy

A tool that can turn ASCII text into art. It is an application with a GTK4 interface that can convert written text into a large inscription made of ASCII characters. It creates quite an eye-catching banner that can be used anywhere. It has a simple interface where you can choose from eleven different font styles.

Halftone

An app that turns your photos into retro computer graphics that look like they’re from the late 80s and early 90s. It uses three different dithering methods, namely the classic Floyd-Steinberg distribution, Bayer matrix scattering and Riemersm scattering. In addition, it can resize images, set the number of colors used, and export images to different formats.

Contour

A cross-platform terminal emulator that works on Linux, Windows, macOS and FreeBSD. In addition to the usual features, it offers GPU rendering, high resolution, support for ligatures in fonts, Unicode and emoji, bold or italic and a lot of other features. If you use it in Windows 10/11 or in the KDE environment, it also offers effects such as transparency or blur.

ReSolve

A multi-platform program with a graphical user interface for calculating electrical resistances. From the results, it can also recommend the types of resistors that are commonly available. After substituting the inputs of the electrical circuit, it can calculate the value of the resistors and select the resistors with the closest value.
