Okay /bant/ I need your help

I love putting my name or symbols on the streets as a sort of sign I was here
But well there's two problems, the first one is that the way I do it is illegal, and the second one is that it's not very original

But recently I saw a movie where a little girl started putting small talismans everywere. And it kinda inspired me to do the same.

Although I have no clue how to build talismans, in what matter, how can they be original, hat sign I should put on them
Do you have any idea?
