Gadget Freak Case #196: Mayan Water Sound Fountain
Here's an entertaining gadget from a trio of engineering students -- a waterfall over a miniature Mayan temple that responds to music. Speakers and lights are built into the Mayan pyramid, and water flows through the center of the gadget for a powerful overall effect. The device includes a pyramid plexiglass body, a water system, a control unit, speakers, and an output screen with LEDs.
Tool_maker, I'm not sure which post you're replying to, but most of the discussion here about young people and mentoring has to do with engineering, not hacking. And I'm not sure why you replied to my comment here, since I didn't say anything in this comments stream about hackers.
@ Jim, Nancy & Ann. What makes you think hackers and those that create a virus do so only because they lack mentoring? I have no supporting statistics, but I believe some people exist whose soul purpose in life is to gain notoriety. We see some doing insane stunts on You Tube, others who shoot up a school or theater and I think the virus writers are cut from the same cloth. If only we could channel their creativity to something beneficial to mankind is a pipe dream. Their goal is to not only be famous, but feared and notorious. Evil people do exist.
