Not a finished artwork per se... this is a web graphic I made for my friend Nick's homepage (go visit him!). I did nearly all the graphics on his page.
Tech notes: All Bryce and Photoshop. To get the effect of night and day in the same picture, I had two versions rendered. I used them as separate layers in Photoshop and then erased half of the top layer using the Airbrush setting of the eraser, to give a smooth transition.
