He constantly sought new techniques and used both primitive and improvised ways of creating visual effects that would later be done electronically. One innovative construction involved attaching a kaleidoscope made from a toilet paper roll to a camera lens with cardboard and tape and setting the resulting abstract images to music. Another was a soup can with both ends removed fitted with angled mirrors. Used on a camera and turning it could put Kovacs seemingly on the ceiling. An underwater stunt involved cigar smoker Kovacs sitting in an easy chair, reading his newspaper and somehow smoking a cigar. Removing it from his mouth, Kovacs was able to exhale a puff of white smoke, all while floating underwater. The trick: the "smoke" was a small amount of milk which he filled his mouth with before submerging. Kovacs repeated the effect for a Dutch Masters television commercial on his ABC game show, "Take A Good Look".
