A designer who wants to see wheelie bins double as public toilets has tested his creation on the streets of London.

Stephan Bischof thinks his 'Pee-lie Bin' could be the solution to the growing problem of public urination in city centre streets.

The Swiss designer has modified the traditional wheelie bin to include a funnel on one side which carries liquid to the base of the bin where it is converted into bio-fertiliser.

Tests in Lewisham, London, showed that (mostly drunk) people were more than happy to use the wheelie bin urinals… though convincing people to put one at the end of their garden might be  bit harder.

Experts claim that wallpaper which emits light could replace lightbulbs, within the next five years.

A Welsh firm has just been given a £454,000 grant by the Carbon Trust to develop their eco-friendly OLED technology.

Bosses at Lomox claim their designs can be used as a thin film to coat almost any surface and light up when a small electric charge is passed through them.

It uses only a fraction of the power of traditional lightbulbs and could be to make almost any item glow and change colour with a natural looking light.

Eventually the lighting OLED film could be used to put TV screens on any surface… and mean you can change your wallpaper at whim.

A US zoo has raised $20,884 (£13,000) this Christmas -- by selling jewellery and other gifts made from Reindeer poo.

For several years Miller Park Zoo in Indiana have taken Reindeer poo and dehydrated and sterilised it before painting it with glitter.

The mess is then fashioned into 'gems' and used to make necklaces, earrings, ornaments and Christmas tree decorations which are sold in the gift shop and online.

This year they produced 300 necklaces and more than 2,000 ornaments which have been sold for $7.50 to £10 to people all around the world.

On hearing the Reindeer poo designs had raised so much money this year, one zoo boss said "No sh*t, really?"

A lego-loving couple are hoping to build a future together, after the little bricks played a big part in their engagement.

When Joe Sparano decided to pop the question to his girlfriend of six years he knew Lego had to be involved.

Their eyes had first met over a box of bricks at a toy store where they both worked, and the pair have regularly bought each other Lego box sets as gifts since they started dating.

So 30-year-old Joe, a graphic designer from Nebraska, started planning a Lego based proposal where he wanted to pop the question to Kristin Kacerik, also 30, at a picnic for their dating anniversary.

The idea of fang mouthed hoodies may sound pretty scary - luckily they are just the latest must-have item of clothing.

These hoodies are the brainchild of Ross Valory who came up with the idea after seeing his friends children crossing their arms elbows pointed out in front.

They opened and closed their arms in a chopping fashion, punctuated of course, by monster noises.

Ross thought it be cool if there was a shirt with a graphic on the sleeves that would form a face with a mouth that would open and close when you put your arms together.

He contacted a graphic artist and started creating the hoodies which allow kids to transform into geckos, sharks, raptors, frogs, dogs, cobras, gators, tigers and orcas.

An artist has painstakingly cut pieces of coloured paper and glued them together to recreate some of his favourite trainers.

David Brownings, from Brighton, says he can spend six hours producing his paper shoes - normally retro Nike Dunk models - which sell for £30 per pair.

The illustrator first came up with the idea while working in a vintage trainer store but since putting his creations online says he had been inundated with requests

Dubbed Nike-elangelo David warns potential buyers that while the shoes might look good on a shelf - they won't wear so well on a basketball court.

An underwear firm has revealed a bizarre new bra which can also be used as a golf putting mat -- after it has been taken off.

The 'Nice Cup in Bra' from lingerie firm Triumph can be rolled out onto the floor to offer practice a 1.5-metre green putting mat.

Players then hit the ball into the breast cups to score, when the ball goes in a voice from in the bra says "Nice in!" The bra has a matching pink skirt and briefs, which when opened, turns into a flag reading 'Be quiet'.

Makers claim the bra - which is not due to go on sale - is their response to the increased number of Japanese women who are taking up golf.

Exactly what they wear while practicing her putting has not been explained.

A design student has created a hat which is guaranteed to make you smile -- because it will poke a spike into the back of your head if you don't.

Lauren McCarthy's "Happiness Hat" is described as a wearable conditioning device that detects if you're smiling and provides pain feedback if you're not.

While it looks like any other wooly hat, it hides a sinister secret, an arm which reaches down your face detects if you are smiling and if your not it inflicts pain.

If the smile sensor detect your smile is turning into a frown it send a message to a battery-powered servo motor which moves a metal spike into the back of your head.

The less you smile, the more painful the spike is said to get - so this is how Santa keeps his elves looking so happy. 

In a bid to make recycling more enjoyable, a group of Swedish engineers have converted a bottle bank into an arcade machine.

The team added flashing lights and an electronic scoreboard to a bottle bank -making it more like a environmentally friendly whack-a-mole.

After pressing the start button, recyclers now see lights above the bottle holes flash, if they get it in quick enough their score goes up, just like the classic arcade game.

The project is part of 'The Fun Theory' scheme by Volkswagen which shows various ways they have attempted to change their behaviour for the better.

Last month they turned a flight of stairs into a giant piano thus tricking people into exercising. (Check out both videos after the link)

A publisher has come up with a novel way of advertising their books… by attaching adverts to flies.

The bizarre advertising campaign was launched (quite literally) by Eichborn at the recent 2009 Frankfurt Book Fair and involved somehow tying tiny ads to the flies legs.

This meant that as the fly took to the air, little banner adverts - which were light enough not to weigh the flies down - appeared to float around the halls.

While the final result certainly looks impressive (check the video after the link) please spare a thought for the poor German work experience kid who probably spent hours the night before tying the adverts to the flies.
