Prizes totaling $3,500 will be distributed amongst the top three winners and a people’s choice winner. Registration ends May 28, 2015 and the submission deadline is June 1, 2015.

Submissions are due no later than June 1, 2015 at 11:59 PM Pacific Daylight Time. Entries should be submitted digitally, in a zip folder.

A $50 entry fee is required with each entry; fees are payable by credit card, Bitcoin, PayPal, and check. If you can’t afford the entry fee, please send an email to [email protected] and request a fee waiver.

Multiple entries from a person or team are accepted. Each entry requires a unique registration number and entry fee. If you plan to enter multiple times, please register multiple times.

Designers should prepare a series of slides which will be reviewed by the judges on computer screen.

Each slide should be a 1280×720 jpeg image (compression set to high).

All supporting text should be on the first slide.

Additional slides should be a series of images or diagrams explaining the design.

One slide should be an image that displays the city in entirety, with the expectation that this could be the image that is reproduced in print media; this image can contain, but is not required to contain, subimages of the buildings or elements of buildings.

Text should be no smaller than 24 px in height, except for your registration number, which should be 12px font in the bottom right corner.

One text document (maximum 1000 words) with an explanation of the design.

A statement identifying the design as the intellectual creation of the designer, licensed as creative commons which 1) allows for adaptations of your work to be shared, and 2) allows for commercial use of your designs.

You will not be judged on the design of your presentation compositions. You will only be judged on the images themselves.
