When you log onto any iOS server, you get a little picture that acts as a title/loading screen.
iClassic's and Ol' West's are similar, and iZone has a signature on the picture with "PxT-un78", and I don't know much about iEra's.
Is there one person at Toonslab/Eurocenter that is in charge for making the pictures, or is it multiple people (thus, the differences between iZ/iE from the similarities of iC and OW, though it may just be an artistic style)...?
