AsciiPaint is a VT100 drawing application leveraging the consoul.net library
You can read more about the project on the consoul.net website docs (asciipaint page)
AsciiPaint can be used to produce enhanced ASCII art. AsciiPaint uses a console window created with the Consoul library to support editing and display of the drawings, so it supports additional features that the Consoul library implements, like using the full (displayable) unicode character set of a font and colors from a 32 bits palette, among others.
