Samo announces at www.yafaray.org:
To celebrate the release of YafaRay 0.1.5. we have organised a summer contest which runs from Juliol 1 to August 26. The contest topic is Vanguardist Architecture. The idea is to depic and render futuristic arquictectural ideas and forms but you could also pay homage to vanguard arquitects and movements from the past. We are looking for awesome modelling and rendering in final works.
