a rolling display label component

[dvd]

Hello:
I wonder if wicket already has a component that would display a list of text 
every n seconds, with the text list predefined  (not ajax call every n second) 
so that I could use a java call like  
new NeonLabel(id,ListModel({ab, cd,ef}, Nseconds)
so that web page would display ab and cd and ef and ab every  N seconds.  I 
have done that in raw javascript but wonder if wicket already has such a 
component?
Thanks
