Space Invaders was launched way back in 1978 and was one of the first Arcade games created.  It is one of the earliest shooting games and the aim is to defeat waves of aliens with a laser cannon to earn as many points as possible. It created such a craze that following its release it casued a shortage of  100-yen coins in Japan, grossed US$2 billion in quarters by 1982 the year i was born ! ! Above is a pair of cuff links that i was commissioned to make with the Space invader theme. You just never know what i will be up to next which is what i love about my work ;0)
