Join the Resistance
Flickr group The Lego Contest Network is hosting, unsurprisingly, a contest. With a wealthy backstory to direct your creativity, you are asked to build a scene of resistance featuring at least a squad and a vignette. Prizes have not been specified beyond being provided by BrickArms (a common prize these days, apparently). Entries are due by April 1st.
By the way, I was particularly pleased by this entry.
