Hour indicator

Description (why)

This solves the problem of not feeling the time when using computer, at the start of a new hour the screen colors will be inverted and go back to normal again (mimicking shock effect in cartoons and anime)

How to use

• install xcalib : for a debian based distro you can use sudo apt install xcalib
• put the script invert_color.sh somewhere (I'm using /home/mossab/git/hour_indicator/invert_color.sh)
• set a new cron job to run it (I'm using user specific conf) :crontab -u USERNAME -e

if this is your first time running crontab it'll ask for default text editor (went with nano)

add the following :0 * * * * bash SET_PATH_HERE/invert_color.sh

• save CTRL-O , exit CTRL+X , Done.

Features

Currently working on

TODO

• adding a transition to the effect would be nice
• set seconds for which effect last from command line (for now you can edit sleep X in invert_color.sh)
