Here is a project that will surely bring a vague smile to those of you reading this. Floating bubble heads is an unusual “installation” consisting of four inflatable spheres that were released on water, just outside Bilbao, Spain. The project greeted the theme of the fifth annual GETZOPHOTO festival, which is “in praise of elderly”. The odd inflatable spheres were wrapped in giant black and white photography, so that they would look like floating human heads. Naturally, elderly subjects were used when choosing the photographs. The result? Four giant floating bubble heads, each one funnier than the next. We do not know if this “installation” had any social impact, but you have to admit the action is of great visual effect. We also uploaded a “making of” video at the end of the post, be sure to have a look!
