where did the power button symbol come from
Power symbol The well-known on/off power symbol was the result of the logical evolution in user interface design. Originally, most early power controls consisted of switches that were toggled between two states demarcated by the words On and Off. As technology became more ubiquitous, these English words were replaced with the universal symbols line "|" and circle "o" (typically without serifs) to bypass language barriers. This standard is still used on toggle power switches.
V sign The insulting version of the gesture (with the palm inwards U+1F594 ðŸ–” Reversed victory hand)[10] is often compared to the offensive gesture known as "the finger". The "two-fingered salute" (also "the forks" in Australia[11]) is commonly performed by flicking the V upwards from wrist or elbow. The V sign, when the palm is facing toward the person giving the sign, has long been an insulting gesture in England,[12] and later in the rest of the United Kingdom, Ireland, Australia, India, Pakistan and New Zealand.[2] It is frequently used to signify defiance (especially to authority), contempt, or derision.[13]
