The 46664 Foundation, named after the number former South African President Nelson Mandela wore while imprisoned for 27 tears, aims to raise awareness and to educate people about the global HIV/AIDS crisis. The campaign began in 2003, when Mandela realized that to reach the youth of the world he needed to engage the support of the people who most appeal to them. Mandela, supported by Dave Stewart of Eurythmics, Brian May and Roger Taylor of Queen, and Bono (natch), persuaded more than 30 of the world's top artists to come together to perform at a global awareness concert for HIV/AIDS in Cape Town.

Mandela will be 90 this year, and to celebrate, as well as to raise funds for 46664, there will be a global launch of limited-edition 46664 wrist bangles during the birthday celebrations in London on June 27. The goal is to create jobs as well as bring at least R1-billion (R=South African Rand, equal to $0.12587 on June 23) to the fight against HIV/Aids. Offered will be 90 platinum bangles (at the cost of R135 660 each), 90 24-carat gold bangles (R67 260), 466 18-carat gold bangles (R54 948) and 46,664 silver bangles (R1 995). The initiative will be a South African effort using metals from local suppliers, the skills of local craftsman and domestic suppliers from the tooling, machining and packaging industries. At least 60 percent of revenues from the sale of bangles will go to the 46664 HIV/Aids prevention campaign.
