Those splinted lines that you see in this tunnel make me think about the near future: interlaced scenarios of moments yet to come. Different possibilities, histories, inflexion points and beakthroughs. This exactly depicts some elements we tackled at the LIFT07 workshop about "designing the future": the thinking about "when change happens".

This is one of the crux element we have to tackle while doing critical foresight: unfolding the history backward from and end point to now, by describing what happenned in the forms of changes/events. The lines here can be seen as a metaphor of two different histories that unfold.
