I was looking about for a jQuery slideshow sort of plugin for the Justice Tracks Collective site. There seems to be the very popular Cycle Plugin. It's quite posh but a bit basic and only deals with <img>
tags. There seem to be a lot of home-made hacks around the place, none of which looked that tremendous to me. I was going to try and write my own hack, but I wasn't really looking forward to it.
Luckily, I found InnerFade, which is posh and simple and works with any sort of nodes. It works great in Firefox. Time will tell if the reason everyone else isn't using it is because it doesn't work in other browsers. Based on my extensive testing with one browser, it's cross-browser support is probably better than the rest of the site.
On another note, I'm enjoying using WordPress for the first time. Still not heaps, but building my own template from very scratch was the best thing I could have done.
