Oberkampf was my first public side project dedicated to code. It was also the first time I had ever interacted with an API. The Flickr API was very new when I made this and there weren't any simple tools that attracted me at time.

Oberkampf was a set of easy functions in php that output different desired Flickr views/feeds. The setup was also very easy to use, as you simply typed in your flickr username and it created the single PHP file you needed to include on your webpages.

When it came out it was cited as one of the top Flickr tools to use. I also once saw it referenced in one of those Flickr hacks books at a Borders bookstore.

The project still exists online however, I wouldn't recommend trying to use it.
