Somehow similar to what Curb does, of whom I speak in this post, Flogos is a company dedicated to break the boundaries in advertising matters. In FLOGOS they create LOGOS that fly.
FLYING + LOGO = FLOGOS.
Based on a patented technology, FLOGOS are basically made up of soap and several gases including helium. They last around 30 to 40 minutes, they can travel up to 50 kilometers (30 miles) and reach an altitude around 5,000 feet.
Besides, these flying logos are 100% environment friendly.
Good idea.
