Pixel Graphics

Is it possible to make pixel graphics/art in Photoshop?

I'm making an app and I wanted to make some backgrounds for different levels and I was wondering if it's possible to create Pixel Graphics/Art in Photoshop. I also have Adobe Illustrator if I can use that too.

Thanks

I think so. Here's a tutorial: https://www.youtube.com/watch?v=hFZBUWHVSrM

Just mess around with the mosaic and pixelate filters bro.
