This Groovlet was written in an effort for me to get some basic understanding of the 500px API and also gain familiarity with Groovlets.
This code will likely evolve and be used, in some form, in a Raspberry Pi photo frame that I plan on building.
The current webserver.groovy file is based heavily on one used in Groovy in Action.
500px shut down public access to their API, so this code will no longer work as-is and will likely be forked in an effort to make the code more generic.
