The images below were made using Durdraw, a program by cmang for creating animated ANSI and ASCII art.
Durdraw is heavily inspired by classic ANSI drawing programs (originally for MS-DOS) such as TheDraw, ACiDDraw and PabloDraw, adding more modern animation features such as frames-per-second control and animated GIF export. It's also made specificaly for Unix-like systems. You can use it to add animation to your shell scripts, or use use CTRL-A and CTRL-E as home and end, for example.
It is in a beta development stage - some features may not yet be implemented, or may be a bit rough around the edges. However, for the most part, it is usable for drawing and animating ANSI and ASCII art.
Durdraw works well in Linux and MacOS X, and will probably work on other UNIX-Like systems like FreeBSD. It requires Python 2.x (2.5 and up works fine). You can download the latest version from the Project page.
A Mac OS X Terminal configuration setup for Durdraw can be downloaded here along with dos437.ttf font which can be downloaded here and should be installed prior to installing the terminal configuration. This is not required, but recommended. The Xterm mouse click can be done (even over ssh) with opt-click or by using iTerm2.
For Amiga fonts dMG's Fonts is recommended.
Here are some screenshot of Durdraw in action running in Linux via SSH in a Mac OS X terminal:
usage: durdraw [-h] [-p PLAY [PLAY ...]] [-q | -w | -x TIMES] [-u UNDOSIZE] [-V] [filename] positional arguments: filename .dur or ascii file to load optional arguments: -h, --help show this help message and exit -p PLAY [PLAY ...], --play PLAY [PLAY ...] Just play .dur file or files, then exit -q, --quick Skip startup screen -w, --wait Pause at startup screen -x TIMES, --times TIMES Play X number of times (requires -p) -u UNDOSIZE, --undosize UNDOSIZE Set the number of undo history states - default is 100. More requires more RAM, less saves RAM. -V, --version Show version number and exit
