Abstract: An actuator for forming a texture layer on a target surface has a housing, a trigger, and an adapter. The housing supports the trigger for pivoting movement between first and second trigger positions. The housing supports the adapter member for sliding movement between first and second adapter positions. The trigger engages the adapter to displace the adapter from the first adapter position to the second adapter position as the trigger moves from the first trigger position to the second trigger position. The adapter engages a valve assembly such that the valve assembly is in closed and open configurations when the adapter is in the first and second adapter positions.

Abstract: There is provided a system and method for an item-based economy in a virtual world. There is provided a server for providing an item exchange for a virtual world lacking a common currency for item valuation, comprising a processor configured to receive a request from a client having an inventory to initiate the item exchange, present a user interface on a display of the client for the item exchange, receive a selection of either a second quantity of second items or a third quantity of third items for the item exchange from the client, remove from the inventory of the client a first quantity of tradable items defined by a first exchange value or a second exchange value based on the selection, and add the second quantity of second items or the third quantity of the third items to the inventory of the client based on the selection.
