The walls of the streets are the canvas. At least during the revolution, the times of oppression and pressure. Forms of street art appear as perhaps the first manifestations of anti-regime defiance and self-expression. These street canvases, like the original Lennon Wall, which was a proud bearer of protest signs and poetry in the 1970s and 1980s, became a free inspiration for the installation The Wall. This 9×4 meter long projection in Lannova park awaits creative revolt and free expression of the collective mind. Visitors to the festival can be involved in the final form of this temporary canvas by means of light torches which draw shapes and various abstract images. They themselves become active participants of revolt, modern digital sprayers, lighthouses in the darkness, which is symbolic for the whole festival. Every active individual, who releases the bridle of his fantasy, is suddenly part of a deeper whole. Because revolution means change. And change is the emergence of the new or unexpected.
