Hoberman disk

 Not an expanding disk. More of a frizball.

An Hoberman sphere that does not expand at the poles. The expansion of each segment increases gradually as the equator is approached. If each segment were under a small amount of tension causing it to want to stay collapsed, then the whole would stay sphere shaped until spun fast enough to cause it to assume a disk shape.
Small tabs along the equator would let you flick the ball which would then fly like a Frisbee until the tension and decreased rotation turn it back into a ball.

I debated whether to post this as a toy or as a spacecraft design, Round in space, and disk shaped for atmospheric flight.

       Would it have an open center like disk in the link? You could throw it over someones head so it strangles that person after spining down. A whole new class of Ninja weapons!

       Nope.   

       My brother for his birthday got this toy which is in the shape of a disk. well actually more of a star like shape which doesn't have pointed edges. Anyway, when you throw it hard enough it flies through the air and the disk turns into a ball. All you have to do is press down on the top and bottom of the ball and it returns to the disk shape thing.   

       I know this is not a very good explanation of the toy so i can understand if people have no idea what i'm talking about.

       [Mind Boggle] does the toy have a name, or can you remember the company?   

       my bro had one of these once...can't recall the name, although it did work like a parallel if the Hoberman sphere were a globe.

       sorry, can't remember the name, i'll keep my eye out for it though. I'm not sure where it is at the moment. If i had to take a guess, i would say it was made by that company "Moose" or something like that. The guys that make crazy putty and all those other little toy thingies

       Don't ask why I know this, but I'm pretty sure you're referring to a "Flatball" [Mind_Boggle].
—RoboBust, Sep 03 2003
   

       Yeah, that's probably it
—Mind_Boggle, Sep 03 2003
   

       I googled Flatball and couldn't find anything other than extreme Frisbee pics.   

       You might chance upon flatball pics if you visit a fatchix-on-top site.

       Could you link your favorite?   

       Well that was totally uncalled for wasn't it, sorry [thumbwax]
I saw what you guys are talking about the other day, (took long enough to get here). The reason it never came up on a search is that it's a Phlat ball. [link] For what it's worth, I swear I never saw one of these before this.
