We caught up with our friends at Positive Posters recently and they've let us know the response to their positive poster design competition has been huge, with entries coming from all corners of the universe.

With this year's theme being 'A glass half full', the entries have ranged from literal to rather obscure interpretations of the theme.

We've taken a peak at the entries to date, and whilst it's hard to pick our favourite, we were drawn to the poster design below from Lynn Cheung. Maybe it's the terrible weather of late in Melbourne, but the purple gumboots featured in this entry really struck a chord with us.

There's still time to enter (submissions close September 10). To find out more or check out the entries to date visit the Positive Posters.
