Google celebrated the 270th Birthday of Alessandro Volta with the following version  (by Mark Holmes)  of their logo on their main webpage worldwide, on Wednesday, February 18th, 2015.  Unfortunately, the graphics use an anachronistic connection between electricity and light  (apparently incandescent light bulbs)  which would only be established decades after the death of Volta.
