The track record and comments on previous projects makes it trustworthy.

Beautifully done

Can‘t tell. I couldn‘t find serious information about anything environmentally or ethically.

Hard to value art and design. The mathematical value is low, because of course you can touch and see it, but it‘s better to do so on a computer.

Not their first rodeo, this is their 18th project.

It looks nice, but of no use. Only the shiny surface one looks good to me.

Metal will last a long time, but really it is using earth's resources for a useless piece of art.

Not a bad price for something like this but more than a useless thing is worth.

Many projects already delivered

Looks cool as a collectible item

No impact

Not expensive, but what are you really getting for it?

defiantly going to do good

Euler Characteristic V-E+F=2, which might look familiar to most in this form, F+V=E+2, where (F=faces, V=vertices, E=edges).

last forever

great price for the precision

it will probably be to the module .

yes....

by design it dose nothing

how do you value something like this... as ART great... anything else....

Yes I have no doubt you will make a mental ring

It is exactly what is intended

Not sure it has much of one

Other then a papper weight for a professor who wants this? Really?

I like some of their previous Projects, but this one doesn't do it for me. I'd rather have the regular donut. 😉

if it cost $20 for a multi-pack, maybe for my desk. But in reality, what does it do?!

Euler Characteristic V-E+F=2, which might look familiar to most in this form,  F+V=E+2, where (F=faces, V=vertices, E=edges)!This is amazing this would be so expensive to have custom CNC-ed for you
