Yeah, I just started a tiny just for fun project on Game Maker: Creating a unique looking OS. So I did.
Here's a mini progress I made so far:

So far the window can drag and drop and close just like Windows/Mac/or Linux. And the "i" icon is internet, which I'm still working on that.


Yeah, the button need more work.

Seems interesting. Exactly what are you using it for?

I'm trying to do a lot of graphic features and helps by other users in the future to test how game maker capability can go. And supernova OS might be the most complex virtual direct x powered OS ever.

That's the thing: virtual. Everything is interpreted via GM's runner.

This does look quite nice, I'd like to see what kind of stuff you can make it do.

New progress:



Now I released an unstable demo for you guys to test it out!

Press key 1 to 5 to change skin.

Since Game Maker OS lack of capabilities. I found this file explorer for Game Maker 6 a long time ago in YoYoGames (It's probably gone) and edited and worked in Game Maker 8. Credit to whoever made the original.
