This was time-travel?

Everything was bright. Nothing seemed solid. People were faint trails in the air, featureless and grey. Cars were vivid streaks of light flashing in and out of existance. Buildings were more nrormal. Solid blocks of darkness. The occasional detail was visible on one or two shop fronts.

"Do you understand?"

Not yet. It was dawning slowly but took a moment to grasp it.

There! A tree, standing at the edge of the park. The tree was vibrant. Though only brown, the colour shone through the mist like a beacon. Form and detail streamed up its trunk. Individual fragments of bark stood out in perfect clarity.

"Yes."

No.

This wasn't time travel, this was merely watching time itself. A living picture of the last centuary. People and buildings coming and going, rising and falling. Colour seeping into itself forming the all encompassing grey fog. Only things which at stood longest were clear.
