Three years ago it was a big round number.
This year, it's the Google logo:
I was three years ago one of those involved in official celebration of Nikola Tesla in Belgrade. We made at the Republic Square in Belgrade a computer cluster driven of course by Free software GNU/Linux and showed on huge screen visualizations of various molecules. Citizens have had an opportunity to see how cluster works, get free CDs of cluster and scientific software. Our cluster exchanged calculations between computers via wireless network since Nikola Tesla was pioneer in wireless communications.
I think that all we owe a lot to such a great mind as Nikola Tesla.
