The retired 69-year old has the free time to invest in his passion.
Especially popular is the intercom system Nermerich installed in a Father Christmas mannequin. Nermerich conceals himself, and talks to kids as if he were the real Father Christmas.
Kids who come to view the display or chat with Saint Nick are given an opportunity to make a donation. When they put their money in a donation box, another mechanical Santa thanks them.
Christmas comes once a year. Once it's over comes the long wait until next year. But when the winter snows have melted and buds begin to emerge on the trees, Nermerich is busy again. With the approach of Easter, he begins once more to cover his house - with the appropriate seasonal decoration - the Easter Bunny.
