Calclear Water Conditioner offers a unique electronic method to eliminate the problems of limescale from home and commercial plumbing systems and appliances. Installation is simple, needing no plumbing and using no chemicals. It?s a simple effective, electronic unit which inhibits scale build-up , creates soft water, reduces maintenance and extends the life of plumbing and hot water systems whilst having low running costs. It works by using a tiny computer chip to generate variable wave forms that change the ability of the mineral salts to crystallise and form the deposits we know as limescale. The changed salts remain in solution where they offer health benefits. www.calclear.com.au

Art that was created during the 1970's and 1980's by South Africa's black artists, has been returned to South Africa by benefactors who had taken it overseas. It now forms a significant part of the Ifa Lethu Heritage Collection. The repatriation of art created by the struggle-era artists, now numbers 670 and required the involvement of 16 countries. Through its work over the last few years, the Foundation has successfully assisted 2,300 poverty stricken youth and women, delivering on benefits such as income generation through job creation and enterprise development. https://www.ifalethu.org.za/

Bus stops have illuminated signs to show where buses are going and when they will arrive. The interior sign also clearly shows the next stop. Our bus was a double decker.
