I wrote a plugin for Adobe Illustrator that lays out a daily calendar on to rolls of wallpaper, showing every day of the week (and highlighting the weekends), for whatever time period you specify.
A calendar for a wall about two meters high can be made to comfortably extend 2oo years in to the past and 200 years in to the future. The wallpaper shows every day of the year for 400 years (about 146,000 days, depending on leap years).
So you can see every day of your expected threescore years and ten lifespan, laid out day by day: it forms a not particularly thick or remarkable band on the wall. Also the lifetimes of other generations, your parents and your children say, overlapping through the years.
The intention is a memento mori effect, and to connect with the continuum of history…
