This is a lovely time-lapse video by videographer Pepijn Koning of the MartiniPlaza venue in Groningen, of which the centre hall seats 4,500.

Earlier this month the Dutch Basketball League play-offs were held here, but in the middle of the play-offs the basketball hall had to make room for a dance hall in which a paint party was to be held (folks dancing while squirting each other with paint).

The video shows how the hall transforms from one type of venue into the other and back again.
