symbol

I read somewhere recently that it's important to have a symbol or something that people can recognize as being your business image. I want to find something so I can put it on my business cards etc. I was thinking immediately of recycling symbols, but I don't want to automatically pick something so obvious.
After doing some research online, I'm thinking more and more about a bats. Yes, bats. Or a single bat...Not only are they good for the environment, but thanks to western folklore they are in fact very COOL! They are pollinators, they eat insects (especially those pesky mosquitos) and they have the ultra cool echolocation which they use to their full advantage. What could be cooler than that?!!! Well, hang on because in other parts of the world they symbolize rebirth. The Chinese regard them with good-luck and happiness. So they represent "protectors of the night" and are good for the environment. And in my book it never hurt to have an association to Bela Lugosi! Yay bats! Now I just have to figure out what bat "image" best represents my business.
