Artist Pat Acton recently completed this enormous 1/26 scale model -- 4.1m long by 2.8m wide -- of the International Space Station, which uses 282,000 matchsticks, 30 litres of glue and 1950 hours of perseverance. He also made modules at 1/13 scale, complete with cutouts that show all the details within the station.
The details are impressive! He even modelled the drawers and racks for science experiments, the toilet, their sleeping quarters... This thing even has a space shuttle at the same scale!
Pat's other models include space station modules as well as the Lord of the Rings' Minas Tirith (420,000 matches), Harry Potter's Hogwarts School (602,000) and the New World Trade Center (468,000), which are also quite impressive.
