Google's logo is looking a bit different today. The primary-colored G-O-O-G-L-E has been swapped for a green and black, boxed-in logo in celebration of Dennis Gabor, the inventor of holography.
Today marks the 110th birthday of Gabor, who was born June 5, 1900 in Budapest (more here).
His invention of holography won him the Nobel Prize for Physics in 1971.
