I have so many planets now! thirty three to be exact.With a bit of photoshop manipulation wizardry I could have twice that. In any case its enough for the long pan background Matt suggested. I did so many because I didn't want it to repeat at all because that would look lazy. However, I can adjust the hues to produce new colours which could look nice to. I have pushed the colours slightly in photoshop to make them slightly more vivid from the original cutouts. They lost some colour during the scanning process.
