8Bit today has a great interview with pixel pusher Helm.  As with previous profiles, Sander gets deep into the philosophy and techniques of the artists he interviews.

An excerpt:

To make a more specific statement I’ll say that pixel art teaches the visual artist to respect the the foundational elements of their chosen genre of work. In pixel art you cannot go any smaller than a single pixel, and so anything you compose has to be made from this finite element, the atom of the digital display. Of course that’s all barring messing with cathode ray tubes in old televisions that displayed pixel art which could do half pixels and less (this inexact realm actually annoys me to think about and I’m very happy the high-tech digital displays of today show a single pixel in all its crisp and lucid beauty). This might seem like a limitation to the beginning artist, but I’ve found that too much freedom makes the artist fear their medium. If you can do anything, where do you start? Limitations breed innovations.
