Is your app the next face of New York City?

Have a knack for coming up with unique and useful photo editing apps? Introducing Photo Hack Day, the perfect opportunity to get some major recognition for your app design skills by putting your face up on the big screen. The REALLY big screen.

On August 20 – 21, Aviary, a multimedia application suite that offers free use of a range of image editors, will host the first annual Photo Hack Day in New York City. Sponsored by NASDAQ, the “hackathon” aims to bring together the world’s best and brightest minds in “photography, photo-editing, web design, computer science and more” to develop “awesome photo hacks using open APIs.”

Participants will have the opportunity to compete for cash prizes, while the selected winners will have their work featured in the NASDAQ Times Square display. Talk about exposure.

A number of companies, including Instagram, Foursquare, Etsy, Pixable and Twitpic, will also be at the event trying to persuade developers to use their applications.

Frank De Maria, NASDAQ OMX Senior Vice President, Corporate Communications, released a statement saying, “NASDAQ has driven grassroots innovation since it created the world’s first electronic stock exchange 40 years ago. NASDAQ is excited to sponsor the 2011 Photo Hack Day at General Assembly and support the start-up community in New York in their pursuit of innovation. We can’t wait to see the results.”
