Google's Doodle by Takashi Murakami

Google changes its doodle frequently to represent some occasion or the other. Today’s doodle of Google is a floral doodle called the "First Day of Summer" by Japanese artist Takashi Murakami. This marks the summer solstice on the Google home page. Murakami was, in 2008, one of Time magazine's 100 most powerful people.
The summer solstice typically occurs on June 21 in the northern hemisphere and December 22 in the southern hemisphere. Though in some years it also happens a day earlier, on June 20 and December 21.
The solstice happens twice in a year, during summer and winter. On a solstice the sun is at its greatest distance from the celestial equator.

During the summer solstice days are the longest and nights shortest and the opposite of this happens on the winter solstice.
Takashi Murakami, born in Tokyo, is a prolific contemporary Japanese artist who works in both fine arts media—such as painting—as well as digital and commercial media. He blurs the boundaries between high and low art. He appropriates popular themes from mass media and pop culture, then turns them into thirty-foot sculptures, "Superflat" paintings, or marketable commercial goods such as figurines or phone caddies. His paintings and wall papers are eye-capturing with pleasing colors.
