Various artists have been inspired in one way or another by the long term, also known as cathedral thinking. A number of interesting examples:

1. The Letters of Utrecht (02000 - as long as there are Saturdays): a poem that is written letter by letter every Saturday in the city center of Utrecht using stones.
2. The Time Pyramid of Manfred Laber in Wemdinge, Germany
3. The Future Library (02014 - 02114) of Katie Paterson in Oslo, Denmark.
4. The Longplayer at Trinity Buoy Wharf in London, a musical piece that lasts 100 years and has been playing since January 1, 2000.
5. The Tropfenstein machine (01996–02496) with which a stalactite is made in a museum in Hamburg.
