Geek Run is a collaborative game played with physical cubes and a webcam. The cubes don’t have any technology inside nor any electronic element, yet they become the interface between the player and the virtual world. By moving them in front of the camera, players control different functional elements on the screen. The lead character follows a series of forking paths. By placing the cubes in the correct position, you help him avoid obstacles and/or opens up a new path in the game. As in a choose-your-own-adventure book, your choices open up new possibilities for gameplay. Thus, the game becomes a never-ending story with infinite number of worlds. This way, every time the installation is presented, the story and the paths are different.The idea is to ask different designers, students at workshops, artists to continue this “exquisite corpse” to shape the journey of our main character. One can choose a path that has not been used yet and decide where it leads, and invent as many paths as he wants. Crossroads can also be made between the different projects and designs.
