The truth of the matter is, the technology that was considered out of this world in the 60s version of "Get Smart" is now at our fingertips, just like the wireless portable shoe phone. We might not wear it, but almost all of us have one.

"Get Smart, the TV series that spoofed U.S. spy operations, also fascinated viewers with its endless array of high-tech and often goofy gadgets. From the Cone of Silence to the Invisible Wall to the Inflato-Coat, to the cigarette lighter doubling as a gun to the two-way wrist communicator and of course the rotary dial shoe phone, what seemed outlandish is now second nature.

Anthony Sparks is operations director at American Surveillance & Security in San Marcos, which sells high-tech "Get Smart"-type gadgets to the public.

"It was thought of as being space-age, and now that it's here and you can actually purchase that item," he said.

Of course, many of the gadgets showcased in the 60s would first have to be updated.

"For instance, even if the shoe phone were available, they'd have to make one now with a hands-free device," Sparks said.

And while there's little demand for a phone doubling as footwear, Sparks says there is a growing market for high-tech ways to spy on everyone from your spouse, to your kids, to your neighbor.

"If you want to see what's inside a sealed envelope without opening it, it's no problem with 'Envelope X-Ray Spray'," he said.

Also popular, the voice changer, which disguises your voice on the telephone, safes that look and work like ordinary aerosol cans and video cameras hidden in pagers, plants, clocks, books and teddy bears.

"This high-tech spy-ware can even be used in what you wear. This tie actually has a built-in spy camera, which can connect to a recording device," Sparks said of one device. "People are just infatuated with the concept that they can actually buy something like that now."
