One day you will die.
It's worth keeping in mind.
This project will generate an A4-sized sheet of paper with a grid containing one square for every week of your expected life (which defaults to 78 years).
If you provide your birthdate, it will x out the ones that have passed and are therefore only part of your fading memory.
The script generates a LaTeX file:
./memento.py > page.tex
You can tell it how many years to generate (default: 78) and have it x off the weeks you've lived if you provide a birthdate:
./memento.py -y 84 -b 1980-07-04 > page.tex
To use an image as the background, use the --background and --opacity flags:
./memento.py --background images/skull.jpg --opacity 0.2 -b 1980-07-04 -y 90 > page.tex
Good opacity values are likely 0.1—0.3, though it will of course depend on what image you are using.
If you prefer, you can use --watermark instead, which will put an image behind the table (opacity doesn't work with this option).
Compile with pdflatex:
pdflatex page.tex
This will produce a file, page.pdf, which you can print out and hang up.
Put it somewhere where you'll see it---every day.
