#
# sudo apt install libcurses-perl
# sudo cpan -I Term::Animation

# Special thanks to @UndeadLeech for adding the transparency. This is
# the *only* fish/asciiquarium without the default black background.

# Thanks to @qmacro for putting rwx into a special fishy.

# Asciiquarium - An aquarium animation in ASCII art
#
# This program displays an aquarium/sea animation using ASCII art.
# It requires the module Term::Animation, which requires Curses. You
# can get both modules from http://search.cpan.org. Asciiquarium will
# only run on platforms with a curses library, so Windows is not supported.
#
# The current version of this program is available at:
#
# http://robobunny.com/projects/asciiquarium
