Djs as well as spinning their sick beats also choreograph dance sections for the crowd. This is a combination of cool stick man style graphics (or better) displayed using projectors and linked to musical hooks. This can make the DJ (or his dance sidekick) even more desirable and get better higher paying gigs at massive rave destinations.
Pre-prepared dance ‘rifs’ could be stored and queued by the DJ for dancing pleasure.
To pull this off we would need some software which can hook into the beat of the music playing to synchronise the moves to the correct musical hooks.
