I was working on a project and went through my links, when I found the link to the NASA 3D models again. When I was home, I powered on the good old Blender 3D and imported the MK3 spacesuit.

You might wonder what a Toscanaut is: This is what you call users of Tricentis Tosca Testsuite. I like the idea. And I am glad I get to work by public transport and do not have to use a rocket (or space shuttle).

Unlimited area but no volume

I was always very fond of the Menger sponge. I built my level 4 sponge manually, not by using a recursive script. You can find a Python script for blender here. Here you will find some renders. I started with a simple lighting, did some reflection afterwards and finally changed the material to glass. Finally I changed the lighting to a two colored one and moved the camera inside. You can play yourself – take the blend file from here (nearly 2,5e6 triangles, 113 MB).

Concerning the headline: The Menger sponge is a strange thing. When the level goes towards infinite, the area does too but the volume goes towards 0.  Tip on the side: Do not try to imagine this sponge 😉

Failure is not an option

I was looking for the origin of the quote “Failure is not an option.”. You find some interesting sources. I still do not know if the source I found is the right one.

I really love the spirit in this quote. And the fact that the origin lies within someone from the Apollo 13 project makes it even more interesting.
