What are your favorite shapes?

I like curves

Stars, hearts, and spheres. But I pretty much like all shapes. I like shapes that don't have names a lot too.

I am particularly fond of toroi.

I have an obsession with stars. I think there is a meaning in it for me.

Paisley.
What about ovoid, bean, rhombus, trapezoid, cartoid, truncated-icosododecahedrons, stellated... ...drons, and my favorite.. paisley forms. There are various stella including the washington monument, and that of the 2001 movie it the form of a draedl or kabbalistic tree-of-life with 9 points of sephiroth and 32 possible paths (like the creation story) connecting them. That's a pyramidal box with a pyramid top. I have some really fancy geometry that couldn't be described easily also based on 3d molecules of the tree. Protein crystallography would be a fantastic pursuit.
Caduceus (double helix snakes)

I also have tons of pyramids around the house, I used to make all sorts of fancy intersections of ovoids, boxes, curved step accordion staircases, in drafting, sculptures, and custom sheet-fab A/C work in Citroëns.

Bad cop, no doughnut.

phallic

mobius

kleinbottle

I guess my favourite shape is the one you get when you superimpose a circle and a triangle.

heart. star, arc(as in rainbows) and "good"--as in "everything is in good shape"

Star

What is toroi?

Kleinbottles should be little Russ-shaped bottles! I'd like those!

yeah that wouldn't be bad at all

What? You forgot dodecahedron?! How could you? Bah!

Spiral!

Are, not is. 'Toroi' is the plural of 'torus' - a solid with a hole in it (like a bagel or a ring or a coffee cup). Hence KR's response.

There are variations, like a doughnut with two holes (or a coffeepot), but I don't know what they are called.

OIC! Thank you! Hare Krishna!

ouch! a mobius, klein-bottle phallus!

hhhhhmmm, the female shape!

Cylinder and dodecahedron.

Pentagram...

Triangle - like an upside down one that looks like a map of Tasmania.

So are you a religious nut?

Not really. I do go to church every week (I fudgeen have to). But how a pentagram makes makes me a religious nut?, because I don't worship a satan.

Why did you choose a pentagram. Is it because you are forced to go to church?

No, it just looks cool.
