The dessert you mention is actually a chocolate (not glass) slipper. It comes in different flavors and types of chocolate. When I sampled one last December, the slipper was made of white chocolate with chocolate mousse inside, covered with a raspberry sauce. Quite tasty, and impressive looking.
It is still available, but must be ordered in advance through the "cake hotline" (407-827-2253 for WDW, and 407-824-7091 for the Magic Kingdom). It is available at Grand Floridian restaurants and at Cinderella's Royal Table.

Regarding the "Build Your Own Lightsaber," I created one a few months ago for my son. This custom-built souvenir can be made at both Downtown Disney's Once Upon a Toy store and at Tatooine Traders in Hollywood Studios (near the exit of Star Tours). For approximately $20 (as of April 2008) you get to piece together either a "Sith" or "Jedi" lightsaber by following the simple instructions provided, and selecting your lightsaber's colors, sounds, etc. If you have any difficulties, the Cast Members in the area are very helpful. Best part about it?...my son STILL uses it almost daily. In my book, that makes it a great souvenir choice!
