Ghrelin—he rocks to live and lives to rock. He’s loud, he’s aggressive, and he lets the child know when he’s hungry. When that hunger is insatiable, he can be deafening. This concept focuses on bringing Ghrelin to life in the form of a loud and disruptive heavy metal musician to demonstrate the intrusive nature of insatiable hunger and the amount of attention it pulls. He induces hunger in his audience by cranking his amps up to the max and filling the room with noise, drawing the child’s attention away from life, making every task more difficult. By making Ghrelin present in every aspect of the child’s life—classroom, recess, bedroom—we can show the true impact it has on those with PWS.
