Before the Landram I build a few paper models which came with a partwork magazine series called "Projekt X". Each issue dealt with a certain topic. They supplied a very informative magazine, a poster and a printed paper kit to cut out and assemble. The magazines and posters survived several moves but the early models unfortunately did not. Among them were a stunning replica of Voyager II in front of a concave 2.5 D background of Jupiter and its moons. When you walked around it the background would move, too, giving the illusion that the space probe was floating.
The other most impressive ones were a star map (which is still in great shape) and a sophisticated sundial.

Someone used the paper plans to build a metal sundial:
The real enthusiasm struck me when I discovered Zealot and the Galactica shippack model project. The work of these guys highly inspired me to start a project of my own. I would never have believed that this would turn me into a (hobby) paper model designer. So far I have made 78, several of them in close collaboration with
@Rhaven Blaack . We joined Zealot at around the same time, he was in for Buck, I was in for BSG, and somehow we met in the middle.
