During the first week of the month the Brilliant Chaos Group on Facebook http://www.facebook.com/#!/groups/brilliantchaosonline/
issues a creating challenge
This year the group is also encouraging a yearlong CHAOS challenge http://www.facebook.com/#!/groups/brilliantchaosonline/doc/544943702200957/
I am still at the stage of thinking about the yearlong CHAOS challenge but in the meantime I am participating in the January challenge.
Silvers Circus http://www.silverscircus.com.au/ is in town in Rosebud; so my challenge response will be to use my photography and art to create opportunities for the Twitter Birds to experience the circus.
