An Interactive Environment for Lua

Disclaimer: I've never actually recieved any of these questions.

Where did that logo come from?

I made it in Paint.NET. And yes, I'm aware that it's blocking the "Overview" link. Just click the pad for now, it'll take you to almost the exact same spot.

Why doesn't my window's icon look like the one in the screenshot?

Probably because you're not using IUP 3. You can check which version you're on by going to the Help menu and choosing "About...".

This is basically just the index page for Copas but rewritten. I don't got time for HTML.
