This is BrickSlounder here with a picture that I made one day when I was bored. As you can see, Benny is enjoying himself in a space background that I made using the program GIMP. I started by using the "generate plasma" function to make a multicolored background layer and added another layer on top of that, and then I used a small elliptical brush with slightly transparent black to cover most of the "plasma." I then added various sizes of what GIMP calls "supernovas" to create stars. I rendered Benny in Pov-ray as a PNG image with a transparent background and added him to the image along with text and the lights on his radio.
Here's more images:
