Design cigarettes with strikable tips. The cigarette packet would have an abrasive surface on one of the box faces against which the cigarette would be struck, negating the need for a match or lighter.

I think that they should make a new type of Ebay - a person who is looking to buy a certain type of item can post it in his listing and the sellers can bid for his business. The seller who has the lowest price will get the business. Isn't that cool?

Introduce bench meters to public parks. These secure coin operated devices would work like parking meters. The new income stream generated would pay for the maintenance and cleaning of existing benches and the purchase of additional benches. Off-peak times (i.e. dusk to dawn) would ensure that homeless individuals electing to sleep on these benches at night could do so without the risk of incurring a financial penalty.

Design a computer with two mice, one for each hand. The non-dominant hand would help with processing tasks rather than typically laying idle.

Introduce digital cameras with built in gags or funny sounds. The gag button could be pressed before the picture is taken as a novel alternative to everyone saying 'cheese'. Camera owners could download refresher gags and noises free from the web.

Design pants with towelling pocket linings for businessmen of nervous dispositions and sweaty palms.

We all know how embarassing an open fly can be. Why not create some type of sensor that senses if your zipper is open and it can sound some sort of an alarm so you can quickly close it before somone else has to be the one to tell you

Introduce parking meters either on public roads or in car parks that can be accessed remotely by telephone. Each space would have its own pin number allowing the owner of vehicle the opportunity to top up their allocated time by credit card payment without returning to the vehicle.

Redesign ice-cream cones to have a channel leading to a reservoir at the base which would collect any drips.

Invent a holder for bathroom products, such as shampoo, shower gel and conditioner that would gently warm them up, thereby avoiding these chilly blobs of cleansing fluids interrupting a nice warm shower.
