5 Rules : 1. Any type of paper can be used. 2. Participants are allowed to paint and glue models if it would not prevent identification of all elements of the model ( including pre-creased lines defining the assembly process). This rule does not apply to the participant s own design. 3. Only photos never published before the olympiad are allowed. 4. Each model should be photographed from at least three angles to clearly display all the details. Low quality photos will not be considered, but total size of the resulting message should not exceed 10 Mb. Recommended size of pictures is from 640x640 to 1500x1500 pixels. 5. Minimal editing of the pictures is allowed as long as it doesn't affect the appearance of the model. E.g. you can crop photos, reduce the noise, change color balance but you must not add, erase or change any details. 6. Participants should not upload photos of their models to the Internet before the end of the Olympiad. 7. Send your results before to origami2015olympiad@gmail.com 4

71 Task 12 Space Sweet Space Maximum score: 15 points In this task we propose you to create your own model. The topic is very broad which allows you to demonstrate your folding and designing skills. You can choose any subject you want if it matches the topic. It can be just starships, astronauts or planet rovers, any space objects and even the ufo, extraterrestrial e.t.c. The model can be created in any style, technique and complexity level. But there still are a few basic rules: - one convex polygon sheet of paper (e.g. square, rectangle, triangle, pentagon, hexagon, etc.); - any color, size, type of paper, etc. - you can use MC+paper, foil-paper, wet-folding as well; - no cuts, no glue; - no painting or varnishing of the finished model (you still can paint the paper before you start folding); - minimal editing of the pictures is allowed as long as it doesn't affect the appearance of the model. E.g. you can crop photos, reduce the noise, change color balance but you must not add, erase or change any details; - you can make a composition photo with as many different models as you like, but only one of them will be judged (you must specify which one is it); - you must include CP or other information about your model (so jury can see that the rules are observed). 70
