Kickroom

Six hard cuts, a different pastel 3D stage for each beat, and the phone arriving a different way every time: tunnel, spin, pedestal, lid, slide.

Soft-toned stages built from simple primitives and plywood: a portal and twisted tunnel, an arch with a slat wall, a tilted tile floor, stepped pedestals and a cube wall, terrazzo, then an empty bright field. A new stage per beat, six in 30.3 s at 124 bpm, bouncy and playful, with flying entrances, spins, unwinding top-down moves and pop-up landings.

Length: 30 s
Scenes: 6
Device: iphone
Style: hyperkinetic
Camera: fast cuts, fly through, top down, turntable
