PRETORIA - The tribute wall at the Mediclinic Heart Hospital in Pretoria where former President Nelson Mandela is being treated for a recurring lung infection continues to grow, as people come out to show their support.

Madiba was admitted to the facility more than three weeks ago.

His condition was said to be critical last Sunday but the Presidency has since said Madiba's condition is stable once again.

Some well-wishers delivered simple notes on white pieces of paper while others pinned up colourful cards with messages penned by children of all ages.

Among the bouquets of flowers and hand painted portraits of Madiba are messages from Pakistani, Sudanese and other nationals living in South Africa.

The police's VIP Protection Services is the latest group to adds its voice of support for Mandela. Dozens of the police's personal security services sang songs praising the 94-year-old.

The officers and civilians said short prayers before placing candles at the tribute wall.

They say the statesman remains in their thoughts.

"We wish our former president good health. We hope God will give him strength," said one officer.

"Get well soon and we love you, Tata."

While the support continues after the last update, South Africans want reassurance from the Presidency on the ailing 94-year-old former statesman's condition.

Madiba's wife Graça Machel and speaker in Parliament Max Sisulu at the weekend indicated that the Madiba was making progress.

A steady flow of well-wishers continues to swell at his Houghton home in northern Johannesburg.

Over the weekend scores of people visited Madiba's Johannesburg residence leaving more flowers, banners with messages, South African flags, candles and balloons.

Tour buses also passed through the area allowing tourists to take pictures of the house that is now colourfully decorated with these tokens of appreciation for the former president.

Madiba moved to his Houghton home in 1990, shortly after he was released from prison. His plan was to retire in Qunu in the Eastern Cape but he has been living in his Houghton home for the past year due to his frequent hospital stays.

Meanwhile, Archbishop Emeritus Desmond Tutu honoured Madiba at the launch of an exhibition of iconic photographs of the former statesman in Cape Town on Sunday.

Tutu shared some of his finest memories of the statesman.

He said Mandela has once again united South Africans, this time in prayer.

Tutu described the period as a sombre moment in South Africa's history.

He said although South Africans' hearts were heavy, they should take the time to realise how far the country has come.

"We come here not to mourn but to remember some of our most precious moments."

Tutu also prayed for Mandela's wife Graça Machel, his children and the rest of his family during this time.
