Just imagined on the day of brexit whole set of islands just started drifting few hundred kms towards west (or south-west given how canary islands often feels like british overseas territory?) to underscore the leaving part.

Dig up beaches on the east coast, dump as landfill on the west coast. Nothing's too much trouble for The Great Experiment.

Of course, Ireland will have to move out the way. (Wait, is this an actual metaphor for Brexit?)
