I want to go on record as saying that this is a most excellent contest idea.
This is the type of effort that pushes creativity and asks directors to move out of their comfort zones and put their minds towards making something that can truly be called good.
I tried to get something like this going with my MovingBricks Ad Contest a while back. A contest that had a fairly narrow start, but which was quite open ended to allow the directors as much freedom to explore and create as possible. With this "Avant-Garde" theme, it pushes directors not towards a goal (such as "make a comedy") but away from old standards.
This is what drives creativity out to new places, to try new things, to explore, to see what can be done and how to do it. Although brickfilming in general "suffers" (from one point of view) by having a membership that consists mainly of younger people, this hobby has been around long enough that there are a lot of older (by year or by maturity) people involved who can see this contest for what it is - a great opportunity.
I would like to thank Cincinnati Bricks for their support of this contest, this hobby and this community. It is only through such generosity that our hobby survives. So thank you, I will be doing whatever I can (however small a contribution it may be) to drive business towards Cincinnati Bricks and promote their business.
As to everyone else: those who don't get it, replace the words "Avant-Garde" with "new".
A film about two guys on a couch playing games is not new.
A film about two guys on a couch playing games as seen from the people inside their heads would be new (like "Hermans Head").
A comedy about a bank robbery with ninja would not be new.
A drama about a bank robbery with consequences would be new (as a brickfilm - there are already shows like this - CSI, NYPD, Starsky & Hutch).
Obviously these are not specific suggestions that should be explicitly followed. You could try other things - play with colours so that your film has hidden actors that can only be seen when a red filter is placed over the screen. Have your film show one scene but be synced and portray a totally different scene if the viewer turns the sound off and plays something else (like "Dark Side of the Moon" and "The Wizard of Oz" simulcast). Have your story delivered in reverse. Have all your characters speak different languages. Watch some old PE Porukka films if you can find them!
Get your thinking caps out! Sorry about the long rant, but this contest has me very hopeful for the future of brickfilming. I had seen a long slide down into mediocrity starting to creep in. This contest seems just the ticket to help stimulate the directors who have started to stagnate.
You don't have to use minifigs as your main charaters!
Smile and say hello to people. It costs you nothing and can brighten their day.
