The image on the wall is the very first scene I tried out back in November 2009 - I think it took a few hours to render!
Took me a few years after that to find my way back here... things have come on a long way since - the same scene behind takes about 2 seconds now!
Input text: A Huge White transparent marble is on a glass bell. The ground is invisible. The sky is a starfield texture. a Small blue light is behind the marble. A purple planet is 1 foot behind the blue light. The top of the planet is 6 inches below the marble. A small green tomato is inside the bell.
A very tiny image-10755 wall is left of and -1.3 foot above the bell.
