Unique, little details...

So besides using a photo booth or cigar roller, what other unique ideas or little details are you doing to make your wedding memorable or unique? I'd love to hear your ideas! I'm thinking of getting a caricature artist for our cocktail hour

we totally tasked about doing the same thing..... we were walking around times square and said we should just one of them lol. I def want to get an acoustic guitar player for the wedding ceremony and cocktail hour to. play fh rock/ metal music.
but we are def doing alot of little inexpensive things though. things to fit our superstitious Fri the 13th theme.
