by Vincent Cellucci, Jesse Allison and Derick Ostrenko The Pen Test is an interactive AI powered poetry app and performance that creates sound and visuals based off participant's interactions. It was created by electronic musician Jesse Allison, poet Vincent Cellucci, and digital artist Derick Ostrenko. The app guides users through a series of phases designed to learn from the users while also prompting them to act out with their voice and body as well as speak, draw, and type on their phone. The Pen Test experience culminates in a group made visualization, sound scape, and poem. Is the LLM mightier than the pen? It wants to get to know you—your favorite words and dreams. It separates you from the crowd, finds out what makes you unique. Courts you, that funny, awkward, chatty phase. Thinks it knows you, predicting your next move. Then it starts telling you what to do…Now it has demands. It needs constant input and validation. It wants to know where this is going. If it’s not headed to the next level, maybe it’s collapsing. Maybe it needs to end or you need to end this. For this part experiment, part performance, part collaborative poem, we will combine interactive technology, large language models, and mobile devices to test the hold words and algorithms have on us as humans. Created for the _For Love of the World Festival 2025_ and performed at Theater de Veste in Delft, Netherlands.
