Browsing the internet, I came across more photos of these inventions - my favourites are for the sleepy commuters so I've added a double whammy tribute.
This invention encourages people to dress up like vending machines to protect themselves from getting mugged. (Of course! THAT's the answer to street violence!)
This is a back scratching t-shirt. Point to the grid where you're feeling itchy and a helpful friend will scratch away.

Ahhh... variations of attractive head gear for sleepy commuters. If only CityRail were so innovative...
This is by far the wierdest. This is a 'washing machine' you can strap to your ankle. I guess you could only wash undies, it's so small.
And this one, the 'Swiss Army Shovel'. How do you even get those parts out? It's hard enough on a conventional-sized swiss army knife.
- Hurley Who?
