The Thursday Theme for this week is some sort of ball or sphere. A Hoberman sphere is actually an icosadodecahedron--a geometric solid consisting of 20 triangles and 12 pentagons. As the sphere expands and contracts, its hubs move in straight lines that radiate from the center. Each point of intersection reinforces the structure. This particular sphere compresses to a 10 inch ball then smoothly expands to a 32 inch sphere.
You can read about the Hoberman Sphere in this article from Wikipedia. If you search for "Hoberman Sphere" on YouTube you can find lots of examples. One is HERE. You can find them in toy stores and museum gift shops or order one from Amazon.com.

and they are actually pretty cool to play with...though i dont think i ever put one on my head...happy tt!
I have seen these but would love to HAVE one to actually manipulate!
Ummm, your friend Mike needs a proper hat.
My first impression was Mike was trying to beat the record for clothes pegs attached to the face.
Never thought of a Hoberman Sphere, simply 'cos I'd never heard of one!
Poor Mike, he'll never score again!
I Want One!
I've played with them before in museum gift shop but I've never worn one.
C'est très drôle et Mike fait la grimace, lol !
Bisous.
Somebody needs to teach your friend Mike how to accessorize. Everybody knows the yellow should be on the bottom so it stands out against the orange shirt. haha
you are so funny.
Great take on the theme. I considered including Buckyballs at one point, but I stuck with flowers.
That expression! LOL~
LOL! Oh my...never seen one before!
Love those things and never knew they had a name/purpose. Great photo too!
Did you find this Hoberman Sphere in the orange and yellow gradation or did you paint it that way?
