Its purpose
This is a tool for curious people who want to learn more about IPs or domains. For example, if you want to know what github.com or google.com are up to, you can use ScanMystique to find out their ports, operating systems, and other stuff. It's pretty fun to use this tool, even though you're not really hacking anything. Don't worry, it's not illegal stuff.
Open Source Code
The best part is, I've made this tool open source and published it on GitHub, so you can take my code and do whatever you want with it. Make sure to give me credit though.
