"Africa Light" - as white local citizens call Namibia. The name suggests romance, the beauty of nature and promises a life without any problems in a country where the difference between rich and poor could hardly be greater. Namibia does not give that impression of it. If you look at its surface it seems like Africa in its most innocent and civilized form.

It oscillates between tradition and modernity, between the cattle in the country and the slums in the city. It shuttles from colonial times, land property reform to minimum wage for everyone. It fluctuates between socialism and cold calculated market economy.

For this quest he dived deep into two spheres that seem to follow different laws but always strive to fathom the magical: physics and art.
