Have you ever wished that your feet could blend in more with their surroundings? Well, now they can! Sao Paulo designer Andreia Chaves has created a pair of “invisible shoes,” which are made from a faceted mirrored surface.

The surface allows the show to reflect different angles of the environment around it, thus camouflaging itself with its surroundings.

After the jump, check out some pictures of more crazy shoes. More...

The United States launched the first hominid into space fifty years ago today. The lucky animal was a chimp named Ham. His name was an acronym for Holloman Aerospace Medical Center located at the Holloman Air Force base in New Mexico.

Ham was one of 40 chimpanzee candidates at Holloman. He underwent a series of evaluations before beating out 39 others for the chance to blast off into space. He was known as #65 before the flight and renamed Ham upon his safe return to earth.

On January 31, 1961 he was launched from Cape Canaveral, Florida on a suborbital flight. While aboard his vital signs were monitored and he was fine. His lever pushing skills were tested as well, proving that tasks could be performed in space.

Optimo 55 Souf was an unknown, aspiring rapper... until he sauntered into the street while doing a dance for his music video and was hit by an ice cream truck. Now he's become a viral video sensation who has soared to stardom with help from Daniel Tosh, host of the Comedy Central show Tosh.0.

In a segment called Web Redemption, Tosh helped Optimo produce a more professional music video, and his song "I'm Gipper" snuck up the iTunes hip-hop singles chart to #15 last week.

Watch the original video here, and then see Tosh's take below.

Those interesting in commemorating Prince William and Kate Middleton’s wedding have a plethora of items to choose from: Mugs, china, coins, and now… condoms.

A company named Crown Jewels has produced condoms commemorating this special day and has already sold more than 1,000.

The company’s website says that their product combines “the strength of a Prince with the yielding sensitivity of a Princess-to-be.”

However, consumers are warned that the condoms won’t actually work in preventing pregnancy; they are just a novelty item after all. Even so, people are snapping up the souvenirs at $8 a pop.

Company spokesman Hugh Pomfret said, “Our prophylactics are designed as an heirloom product. We would encourage people to keep hold of them as a momento of a special national occasion.”

Others are offended by the idea of a picture of Prince William and his betrothed plastered on a condom wrapper.

In more Charlie Sheen news (can there really be more?), the actor voluntarily checked himself into rehab on Friday.

The rehab stint will shut down production on his top-rated comedy, Two and a Half Men. This is the second time in a year that this has happened.

CBS and Warner Bros. Television halted production temporarily. “We are profoundly concerned for his health and well-being, and we support his decision,” they said in a statement.

There is no word yet on how long the actor will be in rehab; however it is his third stint in 12 months.

As if pregnancy and labor weren’t difficult enough, some women have to deal with surprise senior pregnancies, multiple multiples, and babies so light that a stiff wind could blow them away. Here are 5 amazing birth records.

Heaviest Surviving Infant

The world’s heaviest surviving infant weighed 22 lb. 8 oz. and was born in 1955 to an Italian woman named Carmelina Fedele, presumably by C-section. What does a 22 lb. newborn look like? Who knows, but here’s a picture of a 17-pounder.

Lightest Surviving Infant

The world’s smallest surviving infant, nicknamed Tom Thumb, weighed only 9.7 ounces at birth. That’s less than a can of Coke Zero! The baby boy was born in Germany at 25 weeks gestation which is 15 weeks earlier than normal. He arrived in June 2009, but his parents couldn’t take him home until December due to a number of health problems. He is reportedly doing well now, however.
