Wolfratshausen May boys and girls painted their tree - an important moment not only for those in the know. The Kolping family attaches great importance to ensuring that nothing disturbs the perfect white and blue Bavarian look.

The 442 small diamonds on the tree should correspond exactly to the angle of inclination of the diamonds in the Bayern logo. An unclean transition would spoil the entire piece of jewelry. And at a height that passers-by could see for years. From a tree height of 32 meters, the program can paint a diamond pattern of 448 diamonds on a tree. The program was created by Christian Gerardy, 28, who uses a computer program to calculate angles, hypotenuses, offsets, and a calculation program he designed on his laptop. The complex calculation work serves a very useful purpose: the small diamonds should meander around the tree in perfect harmony. This should also help future generations of May Day celebrations to brush the pattern, which is coordinated with gentle transitions, onto their trunks.
