Actually, I had the key rings sitting by the laptop keyboard with the screen tilted down over it to make a little artificial "sky". (See the attachment.) I would like to have had the rings more in the middle of the keyboard so that they would be surrounded on all sides by the overhanging screen, but then I couldn't get the camera in there to take the picture! I think moving the rings farther away from the screen would have made the shadows worse, since the light would really be coming from only one side in that situation.
My next plan is to cut the bottom off a plastic milk bottle, place that over the rings, and then blast it on the outside with bright light. Then I will cut a hole in it somewhere to shoot through and see how that works for a little mini light tent.
Interesting concept! I really like abstracts of household items. It makes us look twice at things we take for granted everyday. I agree with Kim, even if it's not what you wanted, it's still a great photograph. How close were the rings to the laptop? Did you try moving them further away for softer light?
Maybe not what you were going for, but still very interesting. I think you've used the negative space very well and the composition of the key rings makes me look deeper into the image.
