The tracks of my tears and personal data:
All those sadly redundant cables that live in the darkness of our drawers and cupboards. Throwbacks to old equipment and connections, a multitude of ways of doing things in non standard ways that were standard once. The different ideas of joined up thinking and disjointed disposable devices. A competition that was hard to win because there was no finish line, just a vanishing point. The odd lost socks of electronics.
All before the days of the blue toothless, wireless and whatever else that was less and could be under engineered. Progress doesn't care about anything, except for seeing it's own dust in the rear view mirror. Now it's hard to part with these dinosaur bones and so they languish. You never know, they all might come in handy one day. Just not anytime soon.
