Hi Mazeut. Yeah I like the idea here and think it could work. Just a few things though:
1. We can't use readable text in the image (the red up top). If you have text, it usually needs to be small enough to be indecipherable. Check out /pics/techs/ufo_theory for an example.
2. Thanks for providing the GIMP. In the future, though, go ahead and export in PNG not JPG (and you can attach to the forums). Most of our existing techs are JPG but we prefer PNG now.
3. Try to get a little more creative with the "interface" being shown. As mor2 said, you could add some indecipherable details that are flashing up. You could also try and get more of a "screen" look out of the little box, like /pics/techs/alien_base
There are a couple more notes in the attached image.
