Have you ever wondered how the power symbol you see on so many of your electronics came about? Or maybe you wondered why the USB symbol has such a unique shape. The infograph below from Visual.ly delves into the details of some of the more recognizable technical symbols we see on a daily basis.
A note on the design of one of the symbols, the SBBOD (Spinning Beach Ball of Death) is slightly incorrect. Mac users will probably recognize right away that the symbol is not twisted like it is on Mac machines (probably an oversight by a PC designer). The infograph also mentions the “design origins remaining mysterious.” However, the origins aren’t that mysterious. The SBBOD actually came from the spinning CD cursor of the NeXTSTEP machine that Steve Jobs and his team built at NeXT.
