A very annoying reminder.
It's a little Java-Program that opens a window which takes up almost the whole screen, containing a JTextArea with HUGE letters that change their color every 400 milliseconds, telling you to take out the trash. Of course you can edit the text, font, font-size, window-size etc... Just edit the first variables in the Reminder-class. The names are pretty self-explanatory.
I use alarm-clock-applet for Ubuntu to start
reminderStarter.sh at the desired time, which starts the Java-Program.
