I came across this item in a sale flyer that came out today. It is a jigsaw puzzle lighthouse in 3D. It is available in many places in Europe, and possibly in America (Canada and USA), although I did not find it in Amazon.ca or Amazon.com. The finished tower is 8.3 cms (3.25″) wide by 35.0 cms (13.5″) high.
The advertising video on the webpage shows it a bit exaggerated I think. To find the videos look to the right of the two small photos on the webpage, and you will find the videos in two blue boxes labelled TV-Spot and Erklärfilm. One of the videos is here – click your mouse on the blue link.
