Over the years, I’ve played Pacman on platforms from the original coin-operated arcade game, to my PC, my Xbox, my PSP, my Nintendo DS and the iPhone. I never expected I could add playing Pacman inside the Google logo to the list. Now I can, and so can you, in a special Google “Doodle” out today. Today’s Google Pacman logo goes far beyond any special logo that Google has done before. Believe me, I know. I’ve been up close and personal with Google logos as part of my recent story, Those Special Google Logos, Sliced & Diced, Over The Years. This is the first time people have been able to interact with the logo.

It's the soapy wave of the future for advertising - corporate logos made from rafts of helium bubbles which will float serenely above consumers, selling products as they drift. Francisco Guerra, a special effects technician and former stage magician, is behind the fluffy floating logos - or "Flogos", as they are inevitably called.
