Non-planar screens, such as columns, have been a popularmeans for displaying information for a long time. In contrastto traditional displays their digital counterparts aremainly flat and rectangular due to current technologicalconstraints. However, we envision bendable displays to beavailable in the future, which will allow for creating newforms of displays with new properties. In this paper we explorecylindrical displays as a possible form of such novelpublic displays. We present a prototype and report on a userstudy, comparing the influence of the display shape on userbehavior and user experience between flat and cylindricaldisplays. The results indicate that people move more in thevicinity of cylindrical displays and that there is no longer adefault position when it comes to interaction. As a result,such displays are especially suitable to keep people in motionand to support gesture-like interaction.
