Isometric pixel art is an odd sub-niche in the illustration world, a tribute to jaggedy proto-3D video games of the 80s that used the projection. Without pesky vanishing points, you could scroll a background forever, while retaining more depth than a frontal (Duck Hunt) or birds-eye (Spyhunter) projection.

Of course many of these new pieces are taken to the extreme: start with the German collaborative eBoy, and continue on. And if you’re really inspired, try your hand at it. It’s probably the only form of illustration that’s best suited to MSPaint. A couple hints: in Photoshop, lock a guide layer with an isometric grid, and work with the non-anti-aliasing pencil tool (the only good use for that, as well!)

But it does help to really understand the projection, and mechanical illustrator Cody Walker has written two extremely good tutorials on creating isometric illustrations in illustrator. They are non-pixellated, but the same principles apply. Enjoy!
