I’ve used the jQuery Cycle plugin and a few projects and think it’s absolutely fantastic. I was looking at an old project that uses it and began reworking the layout so it would work as a responsive design. This involved using percentages for element widths. This is where the cycle plugin fell down for me as it uses pixels to set widths of elements.

I wrote a simple jQuery plugin to solve this. It has nowhere near the functionality of the Cycle plugin as it only fades between images, but this was the only feature I need at the moment.
