Indexing with hex pixels gets... fun.

You can represent it as row / columns with every second row or column offset, but then straight vertical / horizontal lines turn jagged.

here's a really good collection of hex grid links:

Even moreso, image operations get more fun. Most image filters (and other transforms) assume a regular square grid because the math works out really well (axes are orthogonal and same scale). Any deviations from these assumptions make the math more convoluted. (Pun intended.)

A search for "hexagonal pixel" has lot of relevant and interesting results: https://www.google.hu/search?q=hexagonal+pixel

Do you mean making a screen with hexagonal pixels? That would be really cool, and I think it would just be a matter of changing the shape of the electrodes and crystals (for an LCD).
