You know what just occurred to me? Why hasn't anyone at microsoft or apple invented "dynamic desktop wallpaper" yet? Like sorta a "living desktop background" which moved and seems alive... I can think of some cool desktops right now.
- a space view of the earth where the earth actually rotates real-time
- dynamic clouds that moved and swirled just like RL, and even changed whether and stormed! Lightening optional
- a ocean view with moving waves and swells.
- grassly pasture where the sun slowly moved across the sky (dawn in RL = dawn on wallpaper, night in RL = night in wallpaper... etc.)
- starry sky which occasion comets/meteors and moving constellations.
All uber cool

Anyone know if anything like this is already available?
