Richard Lyall has prepared a set of three video loops for Pentecost and made them available for free download on the EngageWorship.org website. They are 30-seconds in length, but can be set to repeat over and over for use behind liturgy or songs, or to create a mood.
To download a high resolution version (free for use in worship), visit the EngageWorship.org website here.
