Philipp Krebs, a Swiss-born artist who has lived in Cape Town for the past five years, creates unusual and extraordinary public works of art using balloons. In a project called Umbono, a Xhosa word that means vision, Krebs uses larger than life balloons to create awareness and educate people about safe sex and HIV/AIDS. Khopotso Bodibe went to view the Umbono exhibition, and filed this report.
