Liliesleaf "spy room"

Liliesleaf Farm in northern Johannesburg, South Africa, was the farm used secretly by African National Congress activists in the 1960s and was the location where many prominent African National Congress leaders were arrested, leading to the Rivonia Trial. Nowadays Liliesleaf Farm is a Museum and world-famous Heritage Site, attracting many visitors annually, and rated as a top "things to do in Johannesburg" site.

The spy room's concept was to reveal secret relations within the organization and its accomplices by a user operated interactive panel.
