Torreography is an observational game like i-spy based on the geography of towers, hills and spires.
It takes the concept of asterism from astronomy (which means identifying conspicuous nighttime objects in the sky) and translates that practice to reading the terrestrial landscape. The emphasis is on learning observational skills without resort to guides or instruments. There is a relationship here with the skills of pre-industrial cultures such as the first nations of both Australia and North America.
Sometimes you can line up two points from which a third significant point is also in alignment. This is called a syzygy. This can be used to memorise how to see a very distant place of interest on the horizon, such as a building which is otherwise difficult to discern without assistance.
Such low tech observational practices were common in societies before the advent of early scientific instruments. People developed methods for surveying land based on attention and focus. Humans have evolved to exchange information on 'reading the landscape' for the purpose of planning food security. These wayfinding skills were passed down and enhanced through the dispersal of cultural practices in oral storytelling before the printed word.
Today we are distracted so much that techniques which require attentional focus are now providing a therapeutic benefit to address attention deficit. This type of recreational mindfulness is suitable for a range of abilities as the game can be granulated to an infinite number of easy to difficult tasks and range of interests.
