While working at WorkHabit, I helped rebuild and launch WorkHabit.com. Lots of other people were involved, but I probably ended up doing the most theming. Theming on this site was a particularly interesting challenge since there are many transparent PNGs and many non-standard page layouts. There was also a short deadline so there was a week of working extremely long hours trying to get this done, but looking back it's a good memory since such long hours are fortunately not the norm!
