Haunted House Walk

A walk through an old house on the hill after the circus, drawn with code and played by your song: the clowns lead you up to the front door, along a hall whose portraits watch you pass and whose doors slam on the downbeats, into a parlour where a music box plays and a jack-in-the-box springs on the drop, to a mirror that shows a clown behind you, up stairs that never end and back to the entrance hall, where the clowns take their bow and the door opens on the fairground's lights. Fun-house scares, every one a movement, never a flash.

The Front Door

After the show the clowns' lanterns lead you up the hill to an old house: you walk the path a step a beat but the porch never seems to get closer, a curtain twitches upstairs, lightning glows far off, and on the drop the front door swings open and a clown pops up in the light.

The Long Hall

Along the hall a step a beat by your candle: portraits whose eyes follow you, sconces guttering as the song builds, doors that slam on the downbeats, and on the drop a clown springs out of a doorway.

Classic Studio

The Parlour

A music box plays on the table, the clock's pendulum keeps the beat, the curtains lift in the draught and lightning glows beyond the window; a clown rises behind the dust sheets, and on the drop the jack-in-the-box springs open.

Classic Studio

The Mirror

A tall gilt mirror shows the room behind you and your candle; as the song builds a shadow passes in the glass, and on the drop a clown rises behind your reflection and turns to look at you.

Classic Studio

The Stairs

Up the stairs a step a beat, and they never end: portraits climb the wall beside you, the clowns' shadows slide along it by your candle, one peeks over the banister, and on the drop a clown slides down the banister past you.

Curtain Call

Back in the entrance hall the clowns line up under the chandelier and bow on the downbeats, and on the drop the front door swings open onto the night and the fairground's lights far down the hill, confetti falling, and the walk begins again.
