The National Film Board of Canada is looking for proposals for “interactive haiku,” which seems fairly broadly defined: interactivehaiku.com/pdf/haiku_en.pdf )
Intents to enter due August 5; entries due August 19. Entries are accepted in English and French.
Since they’re looking for proposals, not finished works, there’s a fairly low barrier to entry. I expect there will be some neat stuff that comes out of this!
I think they mean it has to be a website, and that it has to include the black bar across the top that interactivehaiku.com/ itself has, with your thing is framed by it. They do say that you must break one of those rules, though, so if that’s a problem for your concept, you could not do it.
