Evil Dead would make a great pin.. Beatles too.. im a massive fan especially during the psychedelic late 60's period.
For a non themed pin.. how about a prison theme.. incarceration.. making a 'tool"... buggery... hiding and selling contraband.. few murders... and instead of a wizard mode we have breaking free.
Bloody love a good prison film, but i dont want some US style gangster, rap dick, yo yo yo, ya know wot im sayin type crap. English prisons are the best..LOL
