Google Australia, China , India and some other places where it’s Saturday already are displaying a special logo doodle celebrating 25 Years of Tetris Effect. The alt text reads “Celebrating 25 Years of The Tetris Effect – courtesy of Tetris Holding, LLC”, and the logo is linked to a search for tetris.

“Tetris … is a puzzle video game originally designed and programmed by Alexey Pajitnov. It was released on June 6, 1984”.

And did you know? One of the original makers of Tetris is now working at Google Australia, specifically, on the Google Wave project.

Sydney Morning Herald reports: “Vadim Gerasimov was just 15 when he was taken under the wing of two Russian computer engineers – Alexey Pajitnov and Dmitry Pavlovsky – at the Moscow Academy of Sciences and helped them create Tetris … Since around 2003 Gerasimov has lived in Australia, where he worked in complex systems research with the CSIRO [Australian Commonwealth Scientific and Research Organization] before joining Google about a year and a half ago.”
