"Licht" by Wolf Leo

A structure made of concrete and mud as 7th station on the "My Way" in Hagenbrunn (Austria) by the german artist Wolf Leo.
Unfortunately, the the ring at the top didn't turn out well and I failed at making it round.
The scan was made for a course named "Gesellschaftliche Spannungsfelder der Informatik" at my university.
