Constitutional Hill was the stage for the making of a coffee mosaic in honour of former president and world icon Nelson Mandela at the weekend.

The "caffeine-rich" artwork was made up of 5,000 cups of Jacob's Kronung coffee under the direction of artist James Delaney.

"I have always wanted to say to him, thank you Tata for making a difference," Delaney said.

He said the artwork was his way of acknowledging the legacy of a leader who touched many lives.

People attending the exhibit where invited to scribble their birthday wishes to Madiba on white paper cups.

The same cups were then used to build the artwork.

The mosaic makes its second appearance this year with a double dose of coffee and a different venue. Last year it took place at Nelson Mandela Square but this year the highest court in the land was the chosen venue.

"I felt we needed to follow Madiba's journey because he was first detained here," he said.

Last year's artwork went viral with pictures appearing in a London newspaper and on the Internet, Delaney said.

Sixty seven minutes of the day was dedicated to teaching young children to play board games. There were bins outside the vicinity where members of the public could donate board games to Active Learning Libraries South Africa. Games ranged from snakes and ladders to Monopoly and chess.

"Playing is imperative for the development of children's minds," library director Heleen Johnson said.

She said the toy library located in Parktown catered for children from Hillbrow, Yeoville and other parts of the city.

According to Johnson, the organisation, which has 200 libraries around the country, provides children from disadvantaged communities an opportunity to play and learn.

Jacob's Kronung senior brand manager Taki Tsanwani said "this year the event was about connecting people beyond their friends and family and reaching out to the rest of the community".

Delaney said he looked forward to another round of coffee art to celebrate the legend's birthday next year.
