Mutant's on the other had do not change any spatial information, instead they modify only the shader - which in fact means you can change/mutate them in strange new ways from the original (including spatially, by way of the vertex shader).

 ### Pixel-art
 
+The style of art Indigo was made for. Pixel art was, in the late 80's - early 90's, the only art style available, and went out of fashion in favour of vector and 3D graphics, as the industry persued ever higher graphical fidelity.
+
+Pixel art can back into fashion in the 00's as a retro kitsch nostaligic throwback, and was largely dismissed again shortly there after.
+
+Modern pixel art is a style in it's own right. It takes advantage of up to date computer graphics rendering hardware and techniques, such as dynamic lighting and a wide colour pallette, while it's blocky nature lends itself to a sort of impressionism, leaving the viewer to fill in the gaps.

 ### TextBox

+A text rendering approach that draws letters to the browsers canvas. This has the advantage of supporting any web font, but the draw backs of being slow and forcibly anti-aliased (smoothed). This means the font looks good at a magnificaiton of 1, but poor at higher game magnifications.
