 a rotary member configured such that rotation of the rotary member changes the relative amount of flow through said flow pathways .  and   a first flow-receiving portion configured to cause rotation of the rotary member in response to receiving a first flow, and a second flow-receiving portion configured to cause rotation of the rotary member in response to receiving a second flow, wherein the first flow pathway is a flow pathway for the first flow and the second flow pathway is a flow pathway for the second flow.   
     
     
         14 . The flow delivery article as claimed in  claim 13 , wherein the rotary member comprises a flow-driven rotary member comprising one or more flow-receiving portions configured to cause rotation of the rotary member in response to received flow. 
     
     
         15 . The flow delivery article as claimed in  claim 11 , wherein the flow control component at least one of:
 comprises a progressive cavity device;   is configured to provide a flow comprising a train of pulses; and/or   is configured to generate vibration and to provide tactile stimulation to a user.   
     
     
         16 . (canceled) 
     
     
         17 . The flow delivery article as claimed in  claim 15 , wherein the first flow-receiving portion comprises a helical element and the second flow-receiving portion comprises a helical element. 
     
     
         18 . The flow delivery article as claimed in  claim 15 , wherein the first flow-receiving portion comprises one or more paddles and the second flow-receiving portion comprises one or more paddles. 
     
     
         19 . The flow delivery article as claimed in  claim 12 , wherein the movable member comprises at least one of:
 a fan arranged such that received flow causes the fan to rotate; and/or   a support member configured to support the movable member in the flow.   
     
     
         20 . (canceled) 
     
     
         21 . The flow delivery article as claimed in  claim 11 , wherein the movable member comprises at least one of:
 a valve; and/or   a rotatable opening configured to permit flow through the first flow pathway in a first rotational position and to permit flow through the second flow pathway in a second rotational position.   
     
     
         22 - 25 . (canceled) 
     
     
         26 . The flow delivery article as claimed in  claim 1 , further comprising a plurality of flow pathways, and a flow control component configured to repeatedly change the relative amount of flow through said pathways. 
     
     
         27 . The flow delivery article as claimed in  claim 1 , wherein the flow control component is configured to cause a plurality of flow changes, thereby providing a time-varying flow.
