This is a remake of the first piece I showed publically, at the Hans und Gloria Festival 2010. Again based on particles, it does not use any particle-particle interactions, but instead relies on movements in an external force field, resulting in fragile filaments and quickly moving threads forming knots and spirals.
While it is pretty easy generate some cool looking spirals with particle traces in a Perlin-Noise field, it turns out to be much harder to give them a satisfying interactive dimension. When the output looks most interesting without touching it, interaction does not add an additional reward, and making reactions to fast movements beautiful while maintaining the “trajectory-memory” property of the traces is hard as well. When tuning the parameters, I decided to focus on the ability of the piece to connect visitors, with acceptable reactions to fast movements and nice effects being created when more than one person works together.
