To celebrate the 50th anniversary of its 911 model, Porsche is presenting a nice musical promotion that uses cars as musical scale syllables. Each of the seven cars, including the vintage and modern versions, are revving their engines to produce seven notes. Each car is “responsible” for one of the tones, depending on the model’s generation—from “c”  for the oldest (1963-1973) through “h”  for the latest (2011-2013).

Comparison stands behind any considered choice, and any confident global brand tends to provide its consumers with an opportunity to examine both the positive and negative sides of their products—and sometimes weigh its offerings against goods by other manufacturer. Sometimes, companies also step outside the product world and help compare lots of other things—sexes, automobiles, brothers, tastes, political parties, athletes and more—to help determine which of the two is better, stronger, messier, tastier, faster, more attractive, reliable, sportive, etc.  In this overview, we won’t focus on serious ratings revealing carbon footprint or social impact, like Nike’s Environmental Apparel Design Tool, Timberland’s Eco Index or GoodWill’s rating—instead, as tribute to April Fool’s Day, which was celebrated last Friday, we will focus on humorous and tongue-in-cheek projects.
