Can anyone tell me what these two sites use for their home page slide shows (carousel)? I would like to implements something similar and I don't want to use flash. I think these modern ones use HTML5 + CSS and maybe JS? I would prefer not to do any JS coding as I am weak in this area.

The two sites are:
http://www.grist.org/
http://labelgmos.org/

If anyone could tell me how they do it and/or a link to a tutorial on how to implement one of those would be greatly appreciated!
Thanks Douglas. I didn't know how to respond directly to you, so I added details. Do you know how they make the lower part that basically has little dots indicating which picture/slide it is on so a user can quickly click on one?
