Some inventions are better than others, then there are some that should never have seen the light of day. Well, maybe they should, if just to make us laugh.

From solar bikinis to a nose worn stylus, these are here to shock. Designers the world over have been creating gadgets that shock. Some might actually be of use but in the real world are they ever actually going to be used? In public? That decision is down to you, so you'll need to see what's out there. Some of them we really can't imagine in the real world outside of these images.

We've collected the most ridiculous, insane, weird and downright odd inventions that have ever been made or conceived, like the Solar Bikini that uses the sun's rays to power any connected device. Thanks to a USB connector a phone can be charged while sunning oneself. Plus, you know, you look like you're from the future thanks to designer Andrew Schneider's hard work. Not bad for $200 then.

While plenty of these you can't lay your hands on, not that you'd likely want to, there are some still available to buy. So if you want to treat this as your slightly off-the-wall shopping list, go for it.

Nose Stylus

Designer Dominic Wilcox came up with the Nose Stylus idea as a means to make multi-tasking even more effective. Looks were obviously less of a consideration, or perhaps he just really liked Clockwork Orange.

Pao Fit

The Fliz

One way to overcome the discomfort of a bike saddle and unnatural motion of pedals is to add a harness to an over-frame with wheels. Obviously. Ideal for downhill speeds then just sort of run like a toddler when on the flat. How this isn't on every street yet is beyond us.

Massage Me

Designed to work with an original PSOne gamepad, the Massage Me, was supposed to let couples enjoy gaming together. By playing the game one partner would be massaging the other as he or she controls the modified game controller. How well this works we can't say, but if you want to give it a go you can make your own using these instructions.

Beauty And The Geek Keyboard Jeans

Dutch design student Erik de Nijs must hate carrying his keyboard around. So, rather than use a laptop, he's integrated a keyboard in his jeans. But not only that, these have a speaker and mouse too. These will set you back £250 for that particular look.

Doryu 2-16 Camera

This camera, from Doryu Camera Company, was created in 1954 as a police issue snapper that not only looked like a weapon but actually made a loud noise like a gun.

Hold hands across the world. This odd little guy mimics the hand holding across an internet connection. You squeeze yours and your child feels his one change like you're there holding his hand. That's not depressing at all.

Don't waste crumbs, feed them directly to the birds. This cutting board vents off the crumbs so you don't have to clear them away, the birds will do that for you. Good luck pumping that outside though.

This product was $15 on Firebox before being discontinued. We can imagine why. It's a noise grenade that could be the most annoying thing in the world.

Getting wet while cleaning an animal can be troublesome. So why not encase yourself in something that a murderer would wear while cleaning up a fresh kill?

Don't act like gripping a fork isn't hard work. We all know it is and that's why the finger fork was born – of real need. Sure. Bung this £1.50 metallic stabber on your digit and eat away without all that grippy holding hassle.

An intelligent umbrella

This is a smart umbrella that lets you know when it's raining. Sounds utterly pointless, doesn't it? Well, maybe not as it does other things too - like notifying you if you've accidentally wandered off without it. This umbrella also has the ability to share data with other smart umbrellas for cloud sourcing data to ensure it's accurate.

A weird workstation

Back in the 70s designers were coming up with weird and wonderful seating arrangements for workers. This included insane things like this figure-hugging chair, built-in typewriter and even some earphones with extendable aerials.
