IBM Inspired Timezone Wallpapers

IBM used to ship Thinkpad laptops with wallpapers that displayed the world and a simplified diagram of the world's timezones. An image search on Google will provide some examples, but none that I could personally use for my computer- usually the resolution was too small. I created these 22 wallpapers using the IBM wallpapers as inspiration. Each image features one timezone highlighted in red on a backdrop of the world. Each continent is shaded in a black and blue gradient, as are the oceans. However, the oceans are also shaded with a series of lines to differentiate them from the landmasses. Each image is 1920x1080 and in PNG format. All 22 images are free for personal use.
