No idea, no plan, no action is taken without connection to the past. Sometimes subliminal, sometimes a acknowledged, and sometimes a parody, the past informs and deeps our appreciation for the time ahead. TiWalkMe arose from two decades of thinking about the limits of human imagination and experience. These links, while not originally connected to those years, are shared to provide context for a visitor new to "deep" time.

Other Deep Time and Ancient Clocks

• The National Institute of Standards- home of the most accurate clock in the world, maintains a fine site on the history of time keeping- curiously (and coincidentally) call a "Walk in Time"
• The September 2002 issue of Scientific American has a wonderful article by William Andrews on mechanical clocks through the ages- but there is a fee. Try the library or ask a friend for a copy of the magazine.
• The Shrine at Ise in Japan is rebuilt every 20 years, counting out the decades since 692 CE. The building, while neither tree nor forest, is a representation of a sacred plant. The Shrine is living proof that communities can nurture such deep time clocks.
• The horologium florae, or clock garden. Originally suggested by Linnaeus, the clock face is planted by different species of flowers that bloom at sequential hours throught the day.
• The "Long Now Foundation" is building a mechanical clock to span the millennia. An example of mankind confusing the measurement of time with internalizing time scales, but the foundation is motivated by some important goals and backers.
• In addition to other speculative uses, Stonehenge may be a clock.
• Other than marking time slowly with the heavens, intra-day clocks are a recent invention- probably only five millennia old. A wonderful water clock, operated only by gravity, surface tension and pendulum is the work of Bernard Gitton. See one of his clocks installed at the Children's Museum of Indianapolis.
• TiWalkMe turns distance into time. Yet others turn time into distance. For example, both the Sternberg Museum of Natural History in Kansas, and the University of Maine have stretched the solar system out along a major highway for hundreds of miles, in a multi-county scale model of the solar system. A drive between planets might take an hour, yet each planet could fit easily within a summer gazebo.
• The million generation foundation, advocating a stone pavement street clock to focus residents to think about a persistent and productive earth.
