This oddly beguiling 1995 documentary by Peter Liechti examines the work and ideas of Swiss experimental artist Roman Signer, who creates “temporary sculptures” in site-specific settings—shooting ribbons into the sky over the mouth of an Italian volcano, setting a table adrift on an Icelandic lake, crashing a toy helicopter into the shutters of an abandoned Swiss inn. Music performances in each locale are woven into a provocative fabric exploring man’s futile attempts to control nature. 81 min.
