Methods of managing virtual resources within a virtual world are described which use a device comprising a connecting element to which one or more smart beads can be attached. A smart bead represents either a virtual resource in the virtual world or an action on a virtual resource in the virtual world. The device is arranged to detect and identify which smart beads are attached to the connecting element and to autonomously update quantities of one or more virtual resources based on combinations of virtual resources and/or actions on virtual resources, where at least one of the virtual resources or actions in any combination is represented by a detected smart bead. In an embodiment, the device is a fashion item such as a wearable device.
