drifter

something is forming in the cloudscape/that defies the nature of cloud/for it seems more substantial than fluff/more angular and designed

as it coalesces/it takes the form of an alphabet block/with a capital B on all the sides/slowly drifting and tumbling/across the sky

it is insubstantial yet holds its shape/except that the letterforms shift/and the Bs become 9s

then the faces become blank

then the Bs come back/hold for three or so minutes/change to 9s/hold (all the while slowly/drifting and tumbling)/for three or so minutes/go blank and stay blank for seven or so minutes/then the sequence repeats

dusk comes and the hard-edged shadow/of the block/melts into the shadow/of the earth

B°9 B°9 B°9 keeps repeating/with the two alphanumerics/becoming subtly contrast-lit/in the growing gloom

then the block stops tumbling and drifting/and takes on an egg shape/oyster-pale and pulsing

and within the egg a sort of 3D cartoon/of a stereotype flying saucer/with a stereotypical humanoid alien/half out of the hatch on top/waving/in looped animation

after a minute of this/the block reforms

but this time the changing alphanumerics/go from B to Y to E to hyphen/twice

then the block vanishes

without a trace
