A ball of light hurtling through an endless series of rings. Like a circus animal jumping hoops, only more direct, more like a rocket.
Only the light wasn't traversing hoops exactly, but milky crystalline spheres-- like a 3-dimensional snowflake or white bone china. Fractally intricate. And the light traversed them one by one, lighting each one up in turn.
Each sphere was a static snapshot of the entire universe. A still model of the universe, in which every detail was faithfully reproduced, but frozen.
As the light plunged on, it would light up each sphere for a tiny instant. There would be the flare of experience. Then it would move on to the next sphere.
I understood the light as consciousness, blazing from one spherical "snapshot" to the next. Time only happens because this consciousness was moving through the series of model-universes, these successive series of film-sets which are otherwise inert.
The string of universe-pearls extended infinitely in both directions, but there was a slight inward curve that suggested the whole thing looped around eventually.
