Creating a complete theme is much more complicated since it involves creating templates for all possible screens used by ShopSite features, pages, products, search, gift certificates, customer registration, shopping cart, wishlist, wordpress, order buttons (order anywhere) and probably some I can't think of. A theme descriptor file, theme_name.xml, needs to be created and it needs to contains all settings that need to be adjusted when the theme is selected . There may also need to be buttons created for all shopper facing screens. The theme must also be added to the themes.dat file that ShopSite uses to know what themes to display on the Preferences > Themes screen. A number of the files that need to be edited are in directories that most merchants would not have access to.
Generally that is more work that a merchant would want to go to for just their store, although a developer or designer or host might want to under take the challenge if they can make money from reselling the theme to multiple stores.
As far as I know there have not been any themes created by anyone except ShopSite. There have been individual templates for pages and products and shopping cart etc created by designers who resell them and there are designers who create custom templates for specific merchants who hire them.
