Awesome! You can also find great art made with Deluxe Paint for the Amiga. The limitations from early computers in resolution and, most importantly, palette, create unique art styles:
Of course, in order to get square pixels, you needed to enable interlace as well.
You can try Screenitron to imitate something like this.
That's how I fell in love with Monkey Island and Flashback
