Retro Building Toys


Playing in a virtual environment with antique & vintage construction toys…


How cool would it be, converting old construction toys into the virtual world? Not only for storing cultural heritage, but also for experiencing these various systems yourself!

I’m focusing on wooden (incl. cardboard) building & construction toys, mainly before 1950. Why? I don’t know yet, but it’s just fun, to rebuild these toys in a virtual world.

As Norman Brosterman said: “Building toys are possibilities, not toys. They are architecture without the problems.” (ref NYT)


For digital building, the free LeoCAD software is used, which is actually designed for playing with virtual Lego. Here you see an impression, how build in LeoCAD, using a Mobaco library:

It’s almost like building in real life!

And combining different construction sets, is also an option, how cool is that!

LeoCAD also provides various export functions, like storing number of parts used (CSV format).


If hope this inspires you, to build (again) with your own favorite building toy or investigating other construction methods!

I also hope, to include many more historical systems, making a big collection of 3D data available, retrofitted into the digital world!

Like the Mobaco story, I cannot do this alone!
I need help from collectors, builders and enthousiasts.

Send me a mail, if you are willing to help me, building an awesome vintage 3D building construction database!
(I’ll provide how-to-help details later.)
