Because the world always need more bash, more bytebeat, more escape sequences, more ephemeral digital art!
There are two main scripts, bansh.sh prints 8-bit colored blocks (spaces with bg color) and basch.sh prints 'ASCII' characters with the current color configuration of your terminal by default (run ./basch.sh -c for color).
Both have a default expression that's evaluated at start, press CTRL+C to edit the expression. Writing a q anywhere in the expression will quit the program. You can also assign an initial expression to any script like ./bansh.sh "t*t>>10". In the case of basch.sh, when using color mode, the expression should be after the -c parameter like this: ./basch.sh -c "t>>((t>>6)&7)&1".
The number of columns is automatically adjusted to powers of two in concordance with the terminal resolution status.
There is a third script that evaluates expressions in blocks of 64 returning the numerical results in order to practice and learn about expressions behavior.
The code is simple and short, edit the value of s variable to change the sleeping time after each line but remember that printing is very CPU expensive.
