Project Playgrounds was an interesting project from a few years back. I was performing some upgrades and enhancements today so was reminded of it.
We were handed a fairly huge number of static files apparently gleaned from an old content management system and were requested to reverse engineer it into our iUpdate CMS and incorporate responsive design (make it work with mobiles). It was a fairly large job and took some time but we managed it.
Project Playgrounds print/paint the designs in schoolyards which are fun educational games designed to keep children's bodies and minds active.
