![]() what part of the palette is effectively applied to the shapes. ![]() In a separate composition, a variety of visual effects are added the laid out layers themselves are coloured with Colorama, taking the lightness channel data in and producing colour out from a palette that wraps around after 360 degrees - this allows freely defining the part of the overall palette where the image begins, i.e. All parameters are changed on each frame and can be re-seeded to allow for different results in the same frames if needed. Each of these layers then gets a base greyscale gradient, each one slightly offset in lightness to have each individual layer follow a part of a greater ramp. Starting from it as a reference, I created a project composing graphics in the same style through randomised procedural generation - allowing change in waves and colours, and automatically creating a corresponding night-time variant.īreaking it down, a fixed number of wave layers are created first and each layer's properties are wired to a series of random numbers bound to expression controls - allowing fine control to the changeable aspects of each layer in a single spot. The default wallpaper on Big Sur is very simply titled "Big Sur Graphic" - it is a saturated, wavy, and energetic piece, definitively digital. Additionally, many Mac wallpapers created by Apple are also dynamic wallpapers and allow either switching with the system's appearance (light and dark modes) or transition naturally with the movement of the sun based on the system's geographical location. With Big Sur that changed again, marking the return to a more abstract default image. ![]() With the release of macOS Mavericks and the decided switch to memorable locations around the state of California, each version also offered a cover shot of the location. While the earlier versions of macOS had less photographic wallpapers set as default, there always was a wider collection shipped with each version besides a primary default paper, available after some browsing in System Preferences past images also used to pick up the respective version's cat name. ![]()
