//OFF TOPIC//I tried that about a month ago with my grandmother's old PC. Hooked the Dell HD straight to it, and tried it first as a main and second as a slave drive. I got nothin' from it both times, so I'm pretty sure everything got cooked.
You could try altering the textures on the space models with the sun graphics in the /assets/textures folder, but it wouldn't animate. It may still look cool, though, so I guess I could try it and see if I can take a few screens to post what it looks like. Only trouble is there's a LOT of space models and twice as many textures.
<.< If I don't come back in five days, send an away team and find me...
