My screen turned black while I was responding to a very urgent message from the African prince. Is this the so called "Darknet" that all the cool kids surf these days?
I would more think of the fungus from The Last Of Us. This fungus really exists (maybe not to this scale pictured) and it controls ants after infecting them. It directly controls their muscles, while growing a fruit body out of the ant's head.
The fungus senses light and humidity. Therefor it climbs plants up and down. The ant is just a vehicle, like a robot body.
Free for the first year and they will eventually charge for the "Standard subscription with ads". You can always upgrade to premium. Hopefully, the adaptive suspension will then start working!
Almost the same situation here. However, my first designs in freeCAD had lots of errors and I experienced lots of crashes and bugs. Didn't really get into it.
My tool of choice is now OpenSCAD. It does exactly what you are designing - not more, not less.
Sounds fair and good for the environment (according to Apple's marketing logic) 👍
