At the river Rhine, the building of the former Bayer headquarters in Leverkusen, Germany, was altered into a giant billboard with more than 5 million LED lights covering a total of 17,500 square meters (188,000 square feet).

The results of all these LED lights is an amazing light show. For those of you who do not believe that this project is real, they made a making of movie of the project (See after the jump). Unfortunately if you do not speak German, it will be hard to understand.

I’m totally owning Sander his post earlier this day, where there is only one tiny post-it light =)

Bayer AG, third largest pharmaceutical company in the world, is well-known for its original brand of aspirin.
