This is an old one, but worth mentioning. The Kellen Construction site. A custom furniture shop that constructed the desks I have in my office. He does high quality work and because it’s custom, you always get exactly what you want. He is most well known for his custom murphy bed construction.
The site is drupal 6, it proved to me how difficult image slideshows can be in drupal 6. I ended up settling on the node slideshow module, but I must say that images galleries in drupal 7 is way better. I’ll write about how I do those later.
