The shape of Brutha's thoughts flickered back and forth in his mind.

Suddenly a real shape flickered across the sky; then another and another.

Shadows and shapes flickered in the corners of the room, but I was laughing too hard to do anything about it, or care.

Its shape flickered, giving glimpses of something else, something that existed in far more than three dimensions.

A few minutes later, when another shape flickered on the edge of his vision, he ignored it.

A dark shape flickered past, a young trout perhaps, but it was gone too quickly to see.

Bits of it had broken off, but this didn't matter; the shape flickered in the air.

Dark shapes flickered around the woman's silhouette, half seen but growing in number.

As data reeled across the bottom of the screen, a graceful white shape flickered into visibility.

His shape flickered for a moment, and then a hand went into the sack.
