The original Hoberman Sphere is an interesting toy.  According to the Wikipedia acticle http://en.wikipedia....Hoberman_sphere , "A Hoberman sphere is a structure that resembles a geodesic dome, but is capable of folding down to a fraction of its normal size by the scissor-like action of its joints....A Hoberman sphere is not a true sphere, but a polyhedron...."

Several LEGO fans have attempted to replicate the Hoberman design using LEGO Technic parts:

1)  Akos Kostyan built a "Magic Sphere Ball" with enough step-by-step photos to make your own ( http://www.mocpages.com/moc.php/5599 ):

2)  Jason Allermann has this version which he displayed at Brickfest 2006 ( http://www.brickshel...y.cgi?i=1990798  ):

3)  Inspired by Jason Allermann's design, Barman made this colorful interpretation ( http://www.brickshel...ry.cgi?f=245253 ):

Maybe its possible to MOTORIZE the opening/closing action via Power Functions.  :cry_happy:    Perhaps you could use the entire range of TECHNIC colors, and make a Hoberman Sphere that looks like Chris Behren's Color Wheel ( http://www.brickshel...ry.cgi?f=431972 ):

On his Flickr photostream, True Dimensions recently posted the picture shown below and a Flickr video of a motorized Lego Hoberman Sphere mechanism that opens and closes the assembly.   :classic:   Centrifugal force makes the sphere expand, then collapse under its own weight when it slows down.  True Dimensions wrote,

"Hoberman Sphere Spinner - Video

Although the Hoberman sphere is pretty stable, it can't really take the repeated abuse of being handled by the public at a show.

I built the spinner so that I didn't have to stand around and open and close it myself, or keep putting it back together.

It works really well when connected to a programmable controller to repeatedly start and stop it."

how have these wonderful pieces gone without comment?! allemann's design is so clean it's sublime, and the display stand is a perfect compliment. i'd have gone with blue instead of the green, but i suspect he was building with what was available in his inventory, hence the abundance of the neutral color.

I built my own Hoberman Sphere and made a video review (kind of):
