With THIS generator you can create wide variety of interessting text-based signatures.
In first dop-down-menu you choose font (style, actually) in which your signature will be created, and right box, were is by default "Type!" write your signature. On the bottom of the site there is option to create picture from your customized signature. I find it very usefull because if you simply copy/paste generated text into your signature area, it will probably come deformed
If you find some interesting font or combination of chars, feel free to share it in comments below :)
