32 years ago I made my first "go into and touch" mobile for my elder son, then 1 1/2 years old. Me, now 64, raised two children, studied art and natural sciences (M.Sc. and Dr. sc. nat. ETHZ), postgrad. studies in archeology, archeotechnology, soil sciences.

I work(ed) as geologist, night duty, teacher, lecturer, lector, welder, lab. technician, horticulturist ...

Now retired, continuing the fascination of craft, balancing, research, patience evolving into the pneumabile balance items.
