there's something wonderful about single tiles. if you strip out the shading and texture, I think the best singletiles tend to have pretty simple structures. The more complexity added to the pattern itself, the harder it is to pull off.
these are bit-for-bit the same tiles, just shifted half a tile horizontally.
how the tile lines up with other parts of the image can sometimes drastically change the way it's percieved, even though the pattern itself is the same.
