This is the sandbox area of this website. In a sandbox you can play, destruct, interact and build nice things. In computer terms a sandbox means that you can play around with scripts, code or designs.
This here is my personal sandbox where I fiddle around with code I wrote. If the script is good enough I will publish it and then other people can fiddle around with it! Every piece of code will get a license on it. If that license permits it, please use my code in your application.
