If the holidays make you feel like time traveling, this piece in the Londonist by Matt Brown will satisfy that itch. "A group of students at De Montfort University created this fly-through of 17th century London (skip to 0:50 in the video to get to the juicy stuff).
The model focuses on the area around Pudding Lane and the bakery of Thomas Farriner, where the Great Fire of 1666 started.
Although most of the buildings are conjectural, the students used a realistic street pattern and even included the hanging signs of genuine inns and businesses mentioned in Samuel Pepys’ diary. More information on the source material and processes can be found on the team’s blog.
The project is an entry in the Off The Map competition, in which students were invited to build 3-D digital models based on maps at the British Library, and using software by Crytek."
