I honestly thought I'd released the gerbers for this project (http://andybrown.me.uk/wk/2013/06/08/a-generic-16-bit-lcd-adaptor-for-the-arduino) months ago but due to an oversight on my part it looks like I didn't do it. Anyway, they're available now so please do visit the downloads (http://andybrown.me.uk/wk/downloads) page if you fancy building your own PCBs.
