At the far right edge is a single red dot.

The face of this species is usually clear yellow with a single dot.

And in the center of the screen now lay a single dot.

A single red dot glowed in its upper left corner.

Then a single red dot flashed in the heart of the blue patch.

The cloud froze and a single dot turned red.

The single red dot glowed in its patch of darkness.

Soon all I could see was one crawling line, which slowed, stopped, became a single bright dot.

The display shrank into a single green dot, then the screen was blank.

And a single dot about twenty metres from the runway.
