Enlighten is my latest contribution to the PmWiki platform. Nothing too special here: a basic 2-column blog layout. But it was easy to produce, and helped me narrow the time it takes to do each part of a skin conversion. Turns out the basic conversion is pretty quick. A few hours. What adds the time is all the extras. Adding fixed/fluid width support; multi-color themes; support for BlogIt. All told, it seems to take around 20 hours to do a skin conversion.
