Artisanal, locally-sourced, organic continuous noise textures, served fresh and always cruelty-free.

Really, this is just a huge pile of seamless continuous noise textures, meant to be used by any code or art project that might need seamlessly-tiling 2D noise. There are several types of noise in the generated/256x256 folder (larger textures should be coming soon):

• value has the lowest quality but still looks decent with enough octaves. It has large blocks of solid colors that fade into their neighbors, but with low octaves it is quite obviously an artificial formation.
• perlin is a big step up from value, even though it's still constructed on a grid; because it effectively places a random vector instead of a flat block of color at each grid vertex, it looks much smoother.
• simplex is usually a step up from perlin, simply because it uses a triangular grid and that makes linear artifacts harder to notice. If you're generating noise in real time, Simplex noise is the fastest of these, but it loses quality if you need 6-dimensional or higher noise (6D noise is mostly used to make seamlessly-tiling 3D cubes).
• honey combines value and simplex and accentuates high and low values; this helps avoid the artifacts that value has, while also avoiding the characteristic "high-low-high-low" value pattern that simplex and perlin have. It improves considerably with 2 or 3 octaves.
• foam is an especially unusual and high-quality type of noise; it's probably the most natural-looking here. It is produced by getting 5 different value results, where each noise call is rotated differently in 4D space, and each noise result shifts the inputs to the next, before all the results are averaged and the highs and lows are accentuated. It changes its character as octaves are added, starting with noticeable light and dark sections, but quickly becoming a fairly realistic cloud. The version here tends to look more "defined" with higher frequency.
