Here, I scaled pentagons with help of small routine, but the best I could get is 220 trapezoids instead of haxagons to finally make 3DSOLID... It looks very difficult to make it from real planar haxagons...

What I meant to say 12 regular pentagons, 20 irregular hexagons and 180 trapezoids...

Where did I hear this, I wonder...

I haven't checked video, but I made presentation of redesign of soccer ball...

Of course, thanks for pushing me to do it... @well20152016 was the one that deserves gratitude too...

Another video, now 3D MODEL of HOUSE based on SOCCER BALL design... Don't quite know for materials, but all faces are planar, so it could be from glass or something flat... It could be very simple, but could be also with larger scales...

This polyhedron has 12 pentagons and 50 quads+triangles... I don't know how Langner sphere is constructed with 12 pentagons and 60 hexagons - this must be some kind of magic I can't imagine...
