When we built JeffreysTea.com earlier this year, owner Jeffrey Hattrick had a very unique request for us: specifically, he wanted his entire site to change color schemes in time with the changing of the seasons. Porchlight MCG+ tackled the problem by creating four sets of underlying graphics and using a combination of dynamically-generated pages and careful page cache policies to switch between them on the fly. The result is a site that changes its entire look and feel four times per year.
