This research focuses on Cristina Iglesias' Diepe Fontein (1997 - 2006), a work that changes and is subject of change. Through this artistic research I show changes in and around Diepe Fontein that have been recorded through reflections. In one cycle of filling (00:13), staying full (00:22), draining (00:20) and staying empty (00:20) I made 80 drawings of 56 seconds each.
