Cool Inventions

I have been getting sucked into shows lately that have people trying to get their inventions on the market.  I usually watch one on the Food Network, where it's all about kitchen-type gadgets, but last night Lloyd was watching one called "Invention USA" and it was pretty cool.  I didn't see the whole show but the part I saw had a couple of guys who made this awesome hydraulic chair with air boosters and it was meant for mechanics to use.  I really don't know squat about cars and fixing them but that chair was amazing!  Every shop should have one to help save some strain on their mechanics bodies.  To be perfectly honest, it kind of looked like it would be fun just to have around the house to play with! :)
