Nonograms, also known as Hanjie, Paint by Numbers, Picross, Griddlers, and Pic-a-Pix, and by various other names, are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden pixel art-like picture. In this puzzle type, the numbers are a form of discrete tomography that measures how many unbroken lines of filled-in squares there are in any given row or column. For example, a clue of "4 8 3" would mean there are sets of four, eight, and three filled squares, in that order, with at least one blank square between successive sets.
Based in France, Puzzle Effects started as a unique take on a set of effects pedals that interlock together like jigsaw puzzle pieces. Without the need of any sort of patch cables. Quirky and unique is always fun, so it is great to see the company move forwards with this idea, to the point where Kickstarter can take it to the next level.
Raster graphics are created and stored using "pixels" to describe the image. Like the pieces of a jigsaw puzzle, pixels are the individual bits, or dots that collectively comprise the larger image. Each pixel has characteristics that affect how the image will look. These characteristics determine things such as whether the image is color, grayscale or line-art, or the amount of the resolution. Pixels are how scanners, computer monitors and digital cameras record and display information. Ultimately, even vector graphics get converted to raster images when they are viewed on or printed. This process is called "rasterization." The device independence of vectors ensures that this will always happen at the highest pixel resolution. 2b1af7f3a8
