My employer's website had a need to expand the functionality of bxSlider, a popular open source responsive image slider.
As my first real forray into contributing to open source, this was a fun little project. You can see my contribution to it on GitHub.
Because I had content that was loaded dynamically based on slide position, I thought that using the browsers forward and backward buttons would be convenient for customers browsing our products. After finishing it, I spent some free time at home reworking and integrating the tool directly. As of right now, my pull request hasn't been accepted, but I still think it's useful.
The end result of the implemented project is available at PlanetLabel.com
