Rob has a nice designers resource page on his web site. Hopefully the ZeppOS Wiki will gain some momentum and become the main destination for documentation.
I was working on a Flash slideshow for an Aloha Media Group project, and I needed to make sure the slideshow background was transparent. I needed to look up the SWFObject code to make that happen, which is:
so.addParam("wmode", "transparent");
I also made sure the to update the slideshow.xml with bgOpacity="0", which I think would have given me the functionality I needed without adding the wmode parameter. I’ll have to test that out.
