I like this. It's a good theme.
I'll suggest a few more, if you can find the original images:
- An Obama logo next to Morena Baccharin, as her image is projected on the bottom of the saucer.
- Substitute Obama for Morena Baccharin on the saucer's projection screen.
- An Obama logo on the podium of the image at the top of this thread.
Maybe your images will go viral, like Registered's "Sore Loserman" masterpiece.
