Claim:
An ice display device comprising: a chill tube that includes a jacket that receives a first thermal transfer fluid, the chill tube having an interior with a cross-section that extends uniformly from an open upper end to an opposing lower end; a piston that slides within the chill tube between the upper and lower ends, the piston providing a fluidtight seal against the interior; a lift coupled to the piston on a side away from the upper end that moves the piston between the upper and lower ends of the chill tube; and a sculpting head coupled to the upper end of the chill tube such that an ice column being lifted by the piston passes through a central opening of the sculpting head, the sculpting head including a plurality of water nozzles arranged to selectively discharge streams of high pressure water from one or more of the plurality of water nozzles into to the central opening of the sculpting head toward a long axis of the chill tube to sculpt an outer surface of the ice column.
