Back in 2004, Patrik Spacek has been working on the Special Edition of the Secret of Monkey Island.
He has done about 20 environments and the character of Guybrush Threepwood. The artworks has been a mix of 3D images, which has been painted over afterwards. It took about 2 months to re-create those environments.
Patrik: "I haven't had any plans to finish this project or release it. It was just a try-out to see how well it can go and the responses from fans over the world has been huge. If I would have a chance to re-create it today, it would look much better, but I would prefer to work on new Monkey Island 2.5 with Ron Gilbert, it would be more fun."
Anyway, the work has been done and here are the screenshots.
