<P> As well as celebrating many well - known events and holidays, Google Doodles are known for celebrating several noted artists and scientists on their birthdays, including Dr. Rajkumar, Andy Warhol, Albert Einstein, Leonardo da Vinci, Rabindranath Tagore, Louis Braille, Ella Fitzgerald, Percival Lowell, Edvard Munch, Nikola Tesla, Béla Bartók, René Magritte, Norman Hetherington, John Lennon, Michael Jackson, Vladimir Dakhno, Robert Moog, Akira Kurosawa, Satyajit Ray, H.G. Wells, Freddie Mercury, Samuel Morse, Hans Christian Ørsted, Mahatma Gandhi, Dennis Gabor, Édith Piaf, Constantin Brâncuși, Antonio Vivaldi, Abdel Halim Hafez, Jules Verne, Leonhard Euler, and James Welch, among over 9,000 others . The featuring of Lowell's logo design coincided with the launch of another Google product, Google Maps . Google doodles are also used to depict major events at Google, such as the company's own anniversary . The celebration of historical events is another common topic of Google Doodles including a Lego brick design in celebration of the interlocking Lego block's 50th anniversary . Some Google Doodles are limited to Google's country - specific home pages while others appear globally . </P> <P> The illustrators, engineers, and artists who design Google Doodles are called "Doodlers ." These doodlers have included artists like Ekua Holmes, Jennifer Hom, and Dennis Hwang . </P> <P> In May 2010, on the 30th anniversary of the arcade game Pac - Man, Google unveiled worldwide their first interactive logo, created in association with Namco . Anyone who visited Google could play Pac - Man on the logo, which featured the letters of the word "Google" on the Pac - Man maze . The logo also mimicked the sounds the original arcade game made . The "I'm Feeling Lucky" button was replaced with an "Insert Coin" button . Pressing this once enabled you to play the Pac - Man logo . Pressing it once more added a second player, Ms. Pac - Man, enabling two players to play at once, controlled using the W, A, S, D keys, instead of the arrows as used by Player 1 . Pressing it for a third time performed an "I'm Feeling Lucky" search . It was then removed on May 23, 2010, initially replacing Pac - Man with the normal logo . Later on that day, Google released a permanent Google Pac - Man site, due to the popular user demand for the playable logo . </P> <P> Since that time, Google has continued to post occasional interactive and video doodles, including but not limited to the following (note the increased frequency in 2016 / 17): </P>
