In Fluke, the 4 company members of Radiohole make full use of their strange and otherworldly set by dancing, climbing and swinging all over it. Many of these maneuvers are done with their eyes closed, after they ritualistically paint fake eyes on top of their eye-lids. Augmenting the mayhem is the use of innovative peek-a-boo technology, an audio spotlight of sorts, which focuses a narrow beam of sound and allows the performers to whisper into the ears of individual audience members.
