Google's logo for today caught my attention, thinking this is a tribute to the Happy Tree Friends. eehh, I was wrong! The logo is a doodle by Takashi Murakami about the First Day of Summer. (aka Summer Soltice)

A solstice is an astronomical event that happens twice each year when the Sun's apparent position in the sky reaches its northernmost or southernmost extremes. It occurs exactly when the Earth's and the moon's axial tilt is most inclined towards the sun, at its maximum of 23° 26'.
