[12] He also presents miniature landscapes and environments in buckets, bottles, mason jars, tins, books, as well as on chess boards and stones.
According to Anna-Louise Mathieu, the instant recognition of Grimm's work "serves as the bait for his insidious trap: no sooner does the esthete, the admirer of the ingenious form flounder in it, than the artist begins to frighten us ... with unsavory details, he sprinkles his cynical observations in between, as if they were chocolate shavings."
He illustrates his world view in "miniature environments thinking about the triangular deals regarding the monopoly of power and capital, about ecological murder, military and technological overkill.
He breaks down the object of his pangs of conscience into bite-proof pieces, and adds a little joke of the bite-sized kind, so that we don't lose our appetite when we are frustrated."
[30] On the occasion of Grimm's eightieth birthday, an extensive exhibition of his complete oeuvre was held at the Museum Voswinckelshof in Dinslaken from 20 August to 15 October 2023.
