Respected designers Armin from Speak Up and Bryan from Coudal actually defend the London Olympic 2012 branding. They list a number of reasons, but they all boil down to one thing: The world hates it, but at least it’s original! Thing is, not only is the logo horrible and the branding just plain wrong for the games, it’s not even close to being original.
Graphics flowing through a city all squiggly-like has been done in a number of ads and music videos, including “Shitty Bum by C-mon & Kypski” (2004 or earlier, by the way). Okay, so that part isn’t original.
What about the psychedelic colour changes? Overused throughout the eighties, the best known example probably being the MTV Launch video (1981).
However, there’s a quote in the aforlinked BBC article which makes me believe it’s not all bad:
Because thank goodness, at least it’s on message.
