Separated at birth: Google Chrome
Category: Separated at birth
I always thought I had already seen Google's Chrome logo somewhere before. And indeed, while far from identical it bears some similarities to ELO's logo from 1977. Both are round, shiny discs with a similar color scheme and docking bay doors in the lower right. More inspiration may have come from the 80ies handheld game Simon and the Pokémon balls.
Mix all ingredients together, shake well and the result is the Chrome logo.
