Just sharing my Star Trek wallpaper...

Made this a few years back for a video game I was working on, unfortunately it never saw the light. Today while going through my old files I found this, thought maybe some of you would like it as a wallpaper - 3840 × 2160 resolution

I've got a second monitor that I glance at for hours every day, so I turned it into a slow-drip learning tool. It's a set of 466 dark-themed wallpapers (2560×1440, scale fine to 1080p and 4K) that rotate as a slideshow:

• All 195 countries: flag, a globe with the country highlighted, a close-up map, capital, population, languages, currency and a fun fact

• All 118 elements, each placed on a mini periodic table

• Maths formulas with diagrams (speed/distance/time, Pythagoras, SOH CAH TOA, area and volume)

• History timelines, the NATO phonetic alphabet, weather, space, first aid, philosophy, art, Roman numerals and more
