"Google Doodle" of the day : Hertz' birthday

Today, Google shows a new "doodle"; the logo has become an electromagnetic wave, in honor of the 155^th birthday of the german phycisit Heinrich Rudolf Hertz :

Today's "doodle"…

…compared with the one for new years day.

Hertz (wikipedia page) was the first (in 1886) to identify invisible electromagnetic waves, that we use today to transmit radio and (terrestrial) television signals. The unit of measurement of the frequency of such a wave is called the hertz, in his honor.

Unlike the recent "doodles" recently featured on Google, this one isn't a technical feat of HTML 5 and JavaScript, but a simple animated gif. Sudden nostalgia attack ! :)
