hypertex asks: "Remember those cardboard tubes you used to look through and see all patterns the crystals produced? I've been looking for a kaleidoscope (for my 3-yr old) and no brick and mortar retailer seems to carry them. Even finding an knowledgeable employee was difficult. Walmart, Toys R Us, Kay Bee, Discovery and Disney stores are just a few to 'just say no' or 'it's too low tech' How can something so simple fade into obscurity? What else is gone?" What are some of the toys that have such a universal appeal that they should never be removed from the shelves? What toys surprised you when they fell into obscurity and what items have shocked you by their ability to stay on the shelves?
