Looks to me like you just go into gimp or wut ever and instead of drawing rlly small images draw big ones, i would use photo shop because with their paint brush tool (i tihnk thts wut its called) has some nice dithering. And if pixels don't work go head for vectors.

Just draw the background image and scroll it slower than the foreground.

To add onto what Longarmx said,

The Farther things are away, the slower they move.
The Closet things are away, the faster they move.
