Geys is known for his photography, painting, sculpture, films, installation art, publishing activities, and experimentation in art education.
Geys is known for the strong social and political motives of his work. He is perhaps best known for his proposal to blow up the Koninklijk Museum voor Schone Kunsten (KMSKA) Museum in Antwerp in 1971 at the end of his solo exhibition held there.
In a letter to the Minister of Culture from November 1970, which was published later in the catalog Ooidonk 78, Geys described his plans about the explosion of the KMSKA as follows: “Departing from the idea that every society, authority, institution, organization, person, etc. includes the seeds of its own destruction, the first and most important task of every society, authority, etc. in my opinion is to recognize, isolate and neutralize these seeds. The most efficient way to achieve all this then seems to me to systematically, scientifically and deliberately set about the problem. […] So I would like to start a project, which, if executed, would result in the destruction of the Museum voor Schone Kunsten.”
